A bending operation is to be performed on the part that has a tensile strength of 600 MPa and a shear strength of 420 Mpa. Determine the blank size required and bending force required when using a v-die with a die opening of 30 mm. Bend factor for edge bending is 0.33 and for V-bending 1.33. What is the total length of the blank to 1 decimal place in mm? 50 70 RIO 30 60
