- A line shaft rotating at 200 rpm is to transmit 20 kW. The allowable shear stress for the material of the shaft is 42 MPa. If the shaft carries a central load of 900 N and is simply supported between bearing 3m apart, determine the diameter of the shaft.o The maximum tensile or compressive stress is not to exceed 56 MPa.The horizontal bar ABC is supported by a pin at A and the two rods with identical lengths and cross-sectional areas (2 sg.in.) The rod at B is steel and the rod at C is aluminum. Neglecting the weight of the bar, determine the stress in the steel rod when the force W= 10 kips is applied. Use Es=29 x 10^6 psi and Ea=10 x 10^6 psi. Express your final answer in psi to the nearest whole number.
