MACHINE DESIGN - An 2-2-1 PROBLEM 2-2 Statement: Determine an approximate ratio between the yield strength and ultimate strength for each material shown in Figure P2-1. Solution: See Figure P2-1 and Mathcad file P0202. 1. The yield strength is the value of stress at which the stress-strain curve begins to be nonlinear. The ultimate strength is the maximum value of stress attained during the test. From the figure, we have the following values of
