Question
Consider a steel bar and a bronze bar on top of one another and set at room temperature between two rigid plates. When this assembly is heated to 500 degree s F, Delta t = 500 degree F What are the stresses in the bronze and in the steel? What will be the change in length of the bronze? of the steel? Given: for bronze bar d = 12 in E = 15,000 ksi Alpha = 11 microinches/deg F Length = 6 in Given for steel bar: d = 6 in E = 30,000 ksi Alpha = 6.5 microin/deg F L = 12 in Consider a solid circular cross section steel shaft (G = 11,000 ksi) of diameter 1 inch fixed rigidly at A and subjected to the following torques: T1 = 5000 in lb AB = 1 ft T2 = 4000 in lb BC = 1 ft T3 = 4000 in lb CD = 1 ft T4 = 7000 in lb DE = 1 ft EF = 1 ft Determine the torque in each segment of the shaft. Determine the maximum shear stress and where it is located. Determine the angle of twist in BC.Explanation / Answer
It's not from any book. My professor made it up. sorry.
