A prismatic bar of length L with a solid circular cross section of diameter d is loaded by a uniformly distributed torque of intensity t per unit distance (see Figure 1) what is the maximum shear stress in the bar? A d Torque intensity = t L Ĉ B

A torsional moment T = 5,382 Nm and a load P = 55,253 N are applied at the same time to a circular hollow shaft of unknown length L, as shown in Figure Q5. The load P is offset from the centre of the circular cross-section by a distance e = 6 mm. The shaft has an inner diameter d = 43 mm and an outer diameter D = 97 mm. Point A in Figure Q5 is on the outer surface of the shaft.      Figure 5   Calculate the direct (or normal) stress in the x-direction σx at point A (the 'x-direction' is along the longitudinal axis of the shaft, along its length L). Use π = 3.14159 if needed. Calculate your answer in the unit: mega-Pascal (MPa). Report you answer to 3 decimal places.
