Strength of Material TextbookTopic: Factor of Safety for Stress LimitsProvide step by step solution You are asked to design a square steel bar out of ASTM A36 steel. The steelhas yield strength of 250MPA (page480). The square steel bar is subjected toa tensile load of 50kN. Your client has asked you to have a safety factor of 3for your design. Determine the required size of the steel rod (side length ofthe square cross section).

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.
An engineer determines that a 32 cm long rod of 1020 grade steel will be subjected to a tension of 40 kN. The following two design requirements must be met: the stress must remain below 120 MPa, and the rod must stretch less than 0.135 mm. Determine an appropriate value for the rod's diameter to meet these two requirements. (Round up to the nearest millimeter when reporting your answer.) mm
