A cold-rolled sheet metal that is 40 mm wide and has a thickness of 5.00 mm is going to be bent into a V shape with a 60° angle. The die opening dimension is 50 mm. Each of the two straight sides of the bent part will be 50 mm long. The bend has a radius of 10 mm. The steel tensile strength is assumed as 400 MPa.
Determine:
a. The required blank size to provide the final workpiece dimensions
b. The force required to bend the part
