Brick Calculations — Engaged Piers


Alright, so now that we’ve worked out how many bricks we have in our dwarf wall the next thing we need to work out is how many bricks through need for our engaged piers and we put our engaged piers to support our wall make a little bit stronger it also provides support for our bearers when we go to put our bearer and joists in so we need to know how many bricks we need in our engaged piers so first thing to work out is where our engaged piers are going to go, and how many that we need So we go back to a plan view and our original dimensions now what we actually need to do is work out. What our internal dimensions are so You take 110mm off each side for a brick and get our new internal dimensions you don’t need all of them you don’t need these two long sides, but you definitely need these 4 short sides So now what we do we’re going to look at each short side by itself so I’m going to take this one here 2150 first. Oh Sorry, our bearers are going to run that way bearer has generally run the long dimension of the building this case It doesn’t matter because it’s equal but they generally run the long dimension of the building So formula is the building length divided by the bearer or our joist spacing plus 1 so as I said I’m going to take this one first this length here and our bearer joist spacing is going to be 1.8m so 2.150 /1.8 +1 Okay Gave us 1.194which we’re going to say 2 always round up in this case plus 1 that gives us three engaged piers along this side So let’s put those in one there on there and one there so there’s our three okay So now let’s still keep going down and look at this one here. So 2.390 /1.8 In this case we don’t need to add the one because we’ve already got this one here so we’re just going to put 1 there and 1 there, so there’s our 2 there and We have a line I have to put one in here a little bit later Okay, so that’s that way done and What we can then do is just replicate whatever’s on this side of the building Same has to happen on this side Okay, this one is not super critical because that Bearers is actually going to be running this way But we try and keep everything in line So everything is evenly spaced Okay, now let’s work our way across this way, so this one’s 2.150 again so we know we’re going to need 3 for that however I’ve already got 2 so we just need to drop another one in the middle there and similarly on this other side We know we needed 2 there before so we can just drop one in there and We need one on this corner, and I tend to put one going each way on the internal Corners Sorry there must be the next step So if we just replicate what’s on these walls up here again keeping everything in line and We’ll end up with that many, and I put one second one on the internal corner So there we go, we have 1,2,3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 engaged piers Okay, so we now we’ve got 17 piers now, how many bricks are in each pier, so if we take the height of our wall which you might remember from the previous video is 516mm so 516 the height of one brick and one brd of mortar which we refer to as a course a course of Brickwork is 86mm high or 0.086 metres high so 516 / 86=6 bricks high for this wall, so then it’s just a simple matter of 17 piers, 6 Bricks per pier Gives us a h102 bricks For this this particular wall, we could of course then allow some waste if you wanted to or you could add the original amount and you could add that to you Dwarf Wall total and then work the waste out at the end So there you go that’s how we work out how many engaged peers we need and how many bricks we need for the engaged pier

How do headphones really work? (4K) – Part 1/5 – “All About Headphones”


Why is it important for me to know why headphones work? Well mostly because it’s interesting about the pussy But also because by knowing how they work and what designs exist you’ll be more capable of narrowing down that perfect pair If you already know how speakers work congrats headphones are designed near identically if you don’t know fear not little one It’s remarkably simple engineering if you crack open the enclosure of just about any headphone You’ll find similarly designed components across the board Inside the headphone enclosure is this little guy. It’s called the driver assembly, and this is where all the magic happens Now the part that produces sound is this dude. It’s called the diaphragm on speakers It’s more commonly known as a cone now The diaphragm is vibrated or more correctly pulled back and forth at Rapid succession Which pushes on the air surrounding the headphones now as you may remember from Junior High school science class? disruptions and displacements in air creates sound waves now sound waves are receptive by our ears and Interpreted or percepted by our brains if you lost me there don’t worry to oversimplify things this diaphragm Which is usually made out of plastic and headphones? produces the sound or music when it vibrates You might be thinking, but how does the diaphragm move there’s no motor on there? Now if we remove the diaphragm from the assembly we’ll find two crucial parts that I’m going to explain Now some headphones and speakers have other parts such as a spider or a pole piece yada yada I’m not going to explain those things if you want to know more I put a link to discovery channel’s how it’s made in the description that well explains all the parts to a driver so the two parts of great importance are these First we have a magnet now the type [of] magnet and the strength vary depending on the headphone Model And that’s not a really great importance Secondly we have what’s called a voice coil. It’s usually a threaded copper wire. That’s it he’s to the diaphragm now when you play music through your headphones say through your iphone you are outputting a certain amount of Through the cable so yes from your headphone jack [all] the way to your ears through the cable is running electricity back and forth now that current goes directly into this concentrated voice coil and as a result it creates an Electromagnetic field now I don’t know if [you] remember from High school physics class But electromagnetic fields are cool because they’re only polarized [for] charge when electricity runs through them So a varying current of the audio signal Causes the voice coil to move up and down Alongside or rather inside the magnetic housing and since it’s attached to the diaphragm it pulls the diaphragm back and forth The diaphragm pushes the Air back and forth and that creates sound waves which is how we hear Cool beans, that’s all there is to it so now you can go brag to all the cute girls in your contact list that you know the ins and outs of drivers and diaphragms Actually, don’t do that This video is a series and consists of several different parts Select the video that you’d like to watch and click on the corresponding annotation if you’re on a mobile device You’ll be unable to click the annotations and thus the links to the other videos are provided in the video description below

Growing Up: How Vertical Farming Works | The B1M


With the global population set to exceed 10 billion people by 2050, the challenge of providing enough food for everyone in a sustainable, efficient and cost-effective way is rising in significance. Shedding the restrictions of seasonal weather
patterns, overcoming transportation challenges and significantly enhancing yields, the growing trend of “vertical farming” could herald the future of food production. For thousands of years, human populations
have farmed the land for food. But with the sharp rise in the number of people on our planet over recent centuries as a result of the industrial revolution, increased living standards and falling mortality rates the pressure on traditional farming has continually
increased. While modern techniques have enabled enhanced
production rates, more than 11% of the world’s total land area is now used for crop production creating environmental challenges that range
from habitat clearing to soil degradation and placing immense pressure on our planet’s
resources. Furthermore, as our cities expand, the distances
between suitable farming land and the large populations who consume its produce are growing,
raising the impact of transportation. Adding to these challenges are a changing climate
that is disrupting seasonal weather patterns and the lack of suitable soils in close proximity
to rapidly expanding areas. One potential solution is the quite literally
growing trend of vertical farming; a concept that sees the sprawling crop farms of old
condensed into much smaller factory-like sites where conditions can be optimised and yields
significantly increased. Facilities like AeroFarms in New Jersey see crop produced in an enclosed environment, where almost everything from the lighting and ambient temperature to soil conditions and nutrients are carefully controlled The facility uses extensive vertical racking to optimise space, as compared to a conventional crop farm enabling it to be located on a far smaller site and much closer to an established urban area Such a location reduces the extent of haulage or “food miles” required to transport produce to consumers, cutting CO2 emissions. Geography aside, the creation of controlled
conditions delivers many benefits. Firstly, the process of crop production is insulated
from seasonal weather patterns that are highly susceptible to disruption as a result of our
changing climate. On a vertical farm, lighting, water and temperature
can all be optimised to remove climatic risks and enhance production rates. As a result, sites like MIRAI’s facility near Tokyo, the world’s largest city, are able generate yields 50 to 100 times greater than that of a traditional crop farm. The use of a controlled environment also eliminates
the losses from birds and insects that must be factored on convectional farms, cutting
the need for harmful pesticides to be used and improving the quality of produce. Vertical farms also optimise the level of
nutrients that crops receive, solving the challenge of finding a sufficient extent of suitable farming land in close proximity to a major urban area. In many instances, soil
is removed altogether, and crops are grown on membranes on membranes where they are sprayed with nutrient-rich solutions. Of course vertical farms do have their limitations
and critics have pointed to the level of energy required to maintain such refined environments. While these concerns are valid, several vertical
farms are powered by renewable technologies and recycle many of their resources. The use of energy efficient LED lighting reduces
power consumption, while the blue and red shades of light are even more economical to run. The optimised crop production process also
allows vertical farmers to reduce the amount of water used, and many vertical farms are
served by rainwater harvesting systems. Some even collect and recycle the water that condenses
within the controlled environment itself. This closed-cycle approach has the added benefit
of preventing nutrients and fertilizers from damaging land or being washed in rivers and
streams. Though the cost and availability of land for
vertical farms in urban areas can prove challenging, many facilities are finding home in re-purposed shipping containers, former factories and disused warehouses. Grander schemes like this proposal by Studio
NAB could even see the vertical farming concept broadened to include the production of fish
and honey while re-connecting consumers with the food production process and establishing
sustainable jobs for the surrounding community. While the vertical concept still represents
a small part of the global food production industry, the benefits it offers to our ever-expanding population could come to tilt the farming landscape by 90 degrees. If you enjoyed this video, and would like to get more from the definitive video channel for construction, subscribe to The B1M!

City at Work- Parks and Rec Fall Facilities


(upbeat music) – Hi, I’m Michael Kowski, Director of Parks and Recreation. We’d like to talk today
about what we’re doing in our facilities across our park system. Many of you have seen some work across our facilities. Some work is done, some is in design phase and some is certainly underway. You may have noticed at
the community center, we opened up a brand new patio space, which is a great spot to host concerts and other such events. Even for rentals. To have your parties kind
of, go from the indoors to the outdoors. It’s a beautiful space. We highly encourage you to check It out. Another great project underway is the senior recreation center renovations. This project will actually
add more square footage to the building, redo some of the finishes in the facility and move some rooms around to be more efficient. Certainly create a
better experience for the seniors who go there
everyday and enjoy the place. Behind me, we have our Old
Settle’s Recreation Center. Old Settler’s Recreation
Center, right now is going through a major renovation. About $4 million worth of work. This is in partnership with our MCDC, who funded this project, in large part. We’ll add brand new space in the facility, brand new bathrooms, a fitness center. Spaces for the community to come and enjoy this great neighborhood asset. The APEX Centre has been
open for a couple years and it’s a great success. And, it’s been such a
great success, that we are, right now, working with
a design team to explore expanding the facility. We’ve heard your feedback.
We need more fitness space, we need more gym space. We need more office space
for our support staff there and we are very excited
to explore those options. We’re also looking at the
outdoor aquatic portion of the project. You know, can we add more
slides and more water features? So, more to come on this and we are very excited to explore this. We are so excited to bring these projects to the city of McKinney,
that we encourage you to visit the Parks and Recreations page on our city website, for more information. (upbeat music)
