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
