A hydraulic punch press is used to punch a slot in a 10-mm-thick plate, as illustrated. If the plate shears at a stress of 350 MPa, determine the minimum force P required to punch the slot. Punch 745 kN 942 kN 450 kN 872 kN 677 kN Slug Plate 20 mm 75 mm Plan view of slug

A circular hole is to be punched in a plate that has a shear strength of 40 ksi. The working compressive stress for the punch is 50 ksi. Determine: a) The maximum thickness in inches of a plate in which a hole 2.5 in. in diameter can be punched. b) If the plate is 0.25 in. thick, determine the diameter in inches of the smallest hole that can be punched. Note: Draw the Free Body Diagram, include the units/dimensions, use the proper formula and round-off all the answers and final answers to 3 decimal places.

Problem 1: The assembly below will be used for each problem. Lengths, diameters, and materials are provided. If the temperature when this system was assembled was 74F, what would be the stress in each cylinder at a temperature of 40F?  Problem 2: If the fixed support at D were removed and the temperature change did not occur, how far would point D move if a 400 lb tension load was applied at the center of each cylinder? (Hint: what sections would you break up the assembly into to find the Normal forces?)  Problem 3: Based on the results from problem 2 and the sections specified in your solution, how much would the diameter of each section shrink from the loads applied? (Hint: Look at Poisson’s ratio for each of the sections listed.
