Question:

A solid steel shaft ABCDE turns freely in bearings at points A and E. The shaft is driven by the gear at C, which applies a torque T₂ = 325 lb-ft. Gears at B and D are driven by the shaft and have resisting torques T₁ = 200 lb-ft and T₃ = 125 lb-ft, respectively. Segments BC and CD have lengths LBC = 20 in. and LCD 5 =15 in. and the shear modulus G =11,600 ksi. Determine the minimum required diameter (d) of the shaft if the allowable shear stress t a 56 ksi. Also, calculate the angle of twist between gears B and D.P
