Computer Aided Design
Time, Cost, Errors etc All headaches such as these related to precad industry have all been drastically reduced. For instance in the example of an exploding cylinder. … You can model that in seconds and then set up FEA experiments in a few more minutes. Then a few more minutes to run them. Excluding the cost of initial purchase of the software the experiment only costs the amount of time required for the CAD monkey to set it up. To setup a physical experiement would be really expensive and really time consuming. As the cylinder would have to be tested first to test the equipment. Then the gauges would have to be attached and then tested. But wait you cant reuse the cylinder or the gauges. The exploding can has been blown up. So you have to do the setup and testing again. Think about it.... EXPENSIVE gauges and technicians arnt cheap. So you might be thinking we should just do FEA. That's a complicated issue. But from my experience the best method is 3 fold! The best things happen in 3's! 1) Theoretical: When coming up with a sketch or a doodle of a design do some math. For me math only cost me a packet of pringles and a glass bottle or irn bru. Once you have decided that it could theoretically be possible move onto the next step... 2) FEA: Build it and test that design. Optimise it using the tools until the design is adjusted so that if performs to the correct spec then move on.... 3) Experimental: Do the physical test to prove the results you got from your multiple FEA studies. If you've got you sum and FEA right you will only have to do this test once. But if you've not got the previous two step right you might have to do it again. From what ive seen, based on result accuracy, this process is like the RAF symbol.... Theoretical is the Blue outer ring, FEA is the White center ring and Experimental is the Red inner ring. Each one is more accurate than the other so you have to balance out what you want to spend with how accurate you want to be.
The cad cell is used in the HV/AC industry as a control in oil furnaces and is made from a chemical compound called cadmium sulfide, which changes its resistance in response t…o the amount of light the material is exposed to.
CAD ( Computer aided design) Uses software to simulate a design of an object on a computer. Which can be changed and manipulated easily before you send off the final design.

Computer could crash, stop working, freeze, etc. Drawings can sometimes be faster and easier to make.
