WARNING I made a dyslexic error when copying the formula. I left out a 7. The formula SHOULD read BA(deg)=(0.0078MT+0.01743BR)xdeg. This error affects all 5 of the non90 videos I made. I will have to reshoot. In the meantime, I will flag the error to make sure no one is harmed! WARNING

This video is an explanation of the math on the FAA Airframe test. You can learn to bend metal without doing this math but this video is about doing the math. It is a follow up to my previous video which explains how setback, bend allowance, bend radius, and sight lines work when bending a radiused corner on the brake. This video explains how we must modify the formulas when doing bends that are not 90 degrees. This is delivered classroom style.
