Checking Engineering Calculations

Checking engineering calculations is a critical part of engineering design. Failure or insufficient checking are the reasons there are failures in designs. Always remember that the more calculations you do, the easier they become. However, this does not ensure that you are immune to mistakes. If you do something wrong once and it works, you'll likely make the same...
