Question
solid constant-diameter shaft is subjected to the torques shown in Figure. The bearings shown allow the shaft to turn freely. (a) Plot a torque diagram showing the internal torque in segments 1, 2 and 3 of the shaft. Use the sign convention. (b) If a solid 1.905 cm diameter shaft is subjected to that particular torque. Determine the maximum shear stress magnitude in the shaft. (c) If the allowable shear stress in the shaft is 80 MPa, determine the minimum acceptable diameter for the shaft.
