Adeep drawing operation is performed in which the inside of the cylindrical cup has a diameter of 4.25 in and a height = 2.65 in. the stock thickness = 3/16 in, and the starting blank diameter = 7.7 in. punch and die radii = 5/32 in. the metal has a tensile strength = 65,000 lb/in2, a yield strength = 32,000 lb/in2, and a shear strength of 40,000 lb/in2. determine (a) drawing ratio, (b) reduction, (c) drawing force, and (d) blankholder force
