Unformatted text preview: metal can withstand before it yields. This measurement of stress (or strength of the metal) is in units of force per area, which in English units is lbs/in^2. Metal handbooks will give you values of yield strength and ultimate tensile strength for various metals. Now if you know the force that will be placed on a metal, you can determine the area over which you can disperse this load in order to never reach the yield point of the metal. This is what I believe is your question in regards to folds, angles or thickness. Different metal shapes have different cross sectional areas that are the in^2 part of the equation....
