Question 3 - Torsion ( A composite shaft is shown in the figure below which is fixed against rotations at ends A and E. Section AC is a solid cylindrical shaft made from aluminium and Section CE is a solid cylindrical shaft made from steel Diameters of sections ACand CE are denoted as dac and dog respectively. Both sections are perfecty joined at C such that there is strain compatibility at the interface. There is a torque Ti applied at the mid-span of Section AC, and a torque T applied at the mid-span of Section CE. Directions of the applied torques are as shown in the Figure. The shear modulus of aluminium is Gat = 50 GPa and the shear modulus of steel is G = 110 GPa The dimensions of the shafts and the magnitude of applied torques are given by: T = 0.5 kNm T = 4.5 kNm dAc = 120 mm dce = 70 mm LAB = LBC = 4 m Lcp = LDe = 2 m Assume the shaft to remain linear elastic during loading.

The figure shows a shaft carrying three gears that rotates at 1150 rpm. Gear A delivers power =10kw to a mating gear that drives a mixer. Gear C delivers power =15kw to a different mating gear that drives a circular saw. All power comes into the shaft through gear B. Draw sheardiagramand bending moment diagram. Considering only torsion, compute the body free diagram and shearing stress in each part of the shaft. Consider stress concentrations, assume the Material is 1144 OQT 1300.
The nodal point on the shaft section is subjected to opposed shear stress, this leads to decrease in the effect of torsional shear stress which increases the fatigue life of the shaft. Select one: O True O False
