A can is to be made with a wall height of 5.0 in. and a diameter of 2.0 in. The sheet metal is 0.015 in. thick, and the wall and base are to be the same thickness. The material has a yield strength of 30,000 psi and an ultimate tensile strength of 40,000 psi. The material is on a coil of strip form, which is 10 ft in length and 10 in. wide.

a. What should be the starting blank diameter, in inches? (6.63)

b. What force is needed to shear the blank from the strip with a guilc. What is the draw ratio for the can? (3.31)

d. What is the percent reduction in diameter? (69.8%)

e. What force is needed to draw the can in pounds? (9858 lb)

f. If the draw ratio was limited to 2.2, what force would be needed for the first draw, in pounds? (8540)
