A cylindrical pressure vessel is made by shrinking a brass shell over a mild steel shell. Both cylinders have a wall thickness of 6 mm. The nominal diameter of the vessel is 750 mm and is to be used in all calculations involving the diameter. When the brass cylinder is heated 50°C above room temperature, it exactly fits over the steel cylinder which is at room temperature. What is the stress in the brass cylinder when the composite vessels cool to room temperature? E for steel=200 GPA E for brass = 100 GPA a for steel = 12 x 10"/C a for brass = 19 x 106/°C Wrong answers will be downvoted

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.
