*So* if you combined blocking with plywood subfloor you'd have a noticeable effect from the blocking above the effect from the plywood. Wood is soft, so we just don't assume we can control it in that situation to the degree required. If you don't understand this, I sympathize, but I can't really explain it very well. To fail entirely in real life, all the blocking has to do is spread the joists out a little bit and slip on a nail in tension, and a lot of people wouldn't even nail it that way to start with. With wood joinery, you don't presume to be able to hold it together in that situation with the sort of fasteners we use. When you say blocking 'obviously' transfers load sideways, you are assuming that it can't just wilt under load. Blocking requires someone to cut each piece. TheyвЂ™re used because theyвЂ™re faster to install, pull them out of the box and put on. Simpson makes metal rafter ties that get nailed on that prevent the twist. Blocking prevents that twist.ДЄs previously mentioned, the blocking helps a little bit to transfer load from joist to joist, but the subfloor also does that, but thatвЂ™s not the primary purpose of the blocking. Holding it vertical with your fist in the center, push down and watch what the ends do, they twist. Now take the yardstick and rotate it vertical so it looks like a floor joist. Take a wooden yard stick and place flat between 2 chairs 35вЂќ apart. So, blocking is installed to prevent the twist. When a long beam (floor joist) is supported on the ends and loaded, the beam twists.

Then add the blocking, and load it with the same load and take the measurements again. Build it, the use extensometers/LVDTs or something to measure the deflection. ThatвЂ™s because it would take a very long time doing the matrices to figure it out without a computer.

A table of fractions of an inch to decimals and millimetres can be found here (opens in new window): Convert Imperial Fractions to Decimal and Millimetres.ДЄ short video showing our cutting list calculator in action can viewed here (opens in new window): Linear Cutting List Calculator Intro Video.It can be calculated, but you need FEA software to do it. NOTE: If your measurements are in fractions of an imperial inch, these will need to be converted from fractions to decimals. Click the 'Print List' button if you would like to print the list of cuts that you have entered. Click the 'Print Visual Cutting List' button if you wish to print the sheet showing the layout.Д§. If you need to remove any cuts from the list, simply click on that particular entry and it will be removed.Д¦. In the 'Cuts' box, enter the length and number of required pieces of steel that are needed for your project and click the 'Add' button after each one.ДҐ. In the 'Stock' box enter any stock that you already have cut.Д¤. The kerf is the width of the cut and will vary depending on the width of the band saw blade or cutting disc that are using.ДЈ. Therefore, if you enter that you need 1 x 6050 mm and 1 x 1950mm, then with a kerf of 1.5 mm, it will want to add another length, so you should enter the exact length of the material (or near to it).Дў. For example an 8 metre length of steel that is sold as 8 metres, may be 10 or more millimetres longer than 8 metres.

A lot of steel is not exactly the length that it is sold as. Your measurements can be in inches, feet, cm (centimetres), mm (millimetres) or metres.

In the 'Settings' box, enter the length of the steel or wood that you will be cutting the required lengths from.
