A punch having a diameter of 19 mm is used to punch a hole in a 6-mm plate. If a punch force of 125 kN is required, what is the average compressive stress in the punch? (A) 441 MPa B 493 MPa 144 MPa 349 MPa

A high-strength steel band saw, 22 mm wide, runs over pulleys 800 mm in diameter. What minimum thickness of the steel band can be used without exceeding a flexural stress of 350? Assume E = 230 GPa. Answer must be in mm.

As shown in the figure, a hole is to be punched out of a plate having a shearing strength of s = 38.95 ksi. The compressive stress in the punch is limited to c = 58.44 ksi. If the plate is t = 0.25 inch thick, determine the diameter (in inches) of the smallest hole that can be punched. Round off the final answer to three decimal places.

P = 8kN. Using N = 3, determine the allowable stress for A501 grade steel. Calculate the dimensions (to 1 decimal place) of a square rod. L = 5.9m. Calculate the deformation (6) and the strain (€).

A rectangular steel block is 75 mm in the x-direction, 50 mm in the y-direction and 100 mm in the z direction. The block is subjected to triaxial loading consisting of three uniformly forces as follows: 24 KN tension in the x-direction, 250 KN compression in the y-direction, and 240 KN tension in the z-direction. If u = 0.3 and E = 200 GPa, Determine the total resulting strain in the z- direction. Note: CN is the last 2 non zero digits of your cellphone number
