The most important factors needed to make a flat pattern layout are

radius, thickness, and degree of bend

When straightening members are made of 2024-T4, you should

straighten cold ans reinforce

If is is necessary to compute a bend allowance problem and bend allowance tables are not available, the neutral axis of the bend can be

found by adding approximately one half of the stock thickness to the bend radius

Select the preferred drawing for proper countersinking.

The flat layout or blank length of a piece of metal from which a simple L shaped bracket 3 inches by 1 inch is to be bent depends upon the radius of the desired bend. The brack which will require the greatest amount of material the one which has a bend radius of
