- You are in charge of designing a new fixture for a “universal testing machine” that will attach a tensile specimen to the machine using a clevis—a U-shaped piece with holes drilled through the two arms—and a cylindrical pin that passes through the clevis and the specimen. If the maximum load exerted by the machine is 30 kN and the pin is to be made of some sort of steel, what is the minimum pin diameter needed to ensure that the shear stress in the pin does not exceed 600 MPa? Assume that the steel has similar elastic properties to pure Fe.Problem 2 You will be determining the value for the external load P that will cause the diameter of BC to change to 5.8 mm. The original diameter of BC is 6 mm. Use the values given below unless otherwise stated by the questions. E = 200 GPa V = 0.38 300 mm 400 mm B 1 -200 mm-Round off to 3 significant figures, and the tolerance is ±1 in the 3rd significant digit. Thank you.
