We are trying to determine what tonnage is required for the following operation.

Material: 7/16" x 15" x 78" HR A-572 gr.50 steel plate.
Yield 70,000 psi.

Operation: Need to put a 7 degree air bend on the 78" length. our bottom brake die has a 3" opening.

Tonnage required in a hydraulic press???

Thank you.
