Webb10 jan. 2024 · Bend allowance considers the thickness of the sheet metal, the bend angle, the method employed, and the K-factor (a constant used in sheet metal bending calculation that allows the estimate of the amount of stretch of a material). It is a measure of the ratio of compression on the inside line of a bend to the tension on the outside of the bend. WebbMultiplying both sides times 40, you're going to get, let's see. 40 divided by 30 is 4/3. 4/3 sine of 40 degrees is equal to sine of theta, is equal to sine of theta. Now to solve for theta, we just need to take the inverse sine of both sides. So inverse sine of 4 over 3 sine of 40 degrees. Put some parentheses here, is equal to theta.
