(USCS units) A deep drawing operation is performed on a sheet-metal blank that is 1/8 in thick. The height of the cup = 3.8 in and its diameter = 5.0 in (both inside dimensions).

(a) Assuming the punch radius = 0, compute the starting diameter of the blank to complete the operation with no material left in the flange.

(b) Is the operation feasible (ignoring the fact that the punch radius is too small)?
