Question
A brass rod 8mm diameter and 400mm long fits centrally inside aluminum tube of the same
length having an external diameter of 16mm and a wall thickness of
3mm. The rod and tube are rigidly connected at their ends so that they twist together when a
torque of 20 Nm is applied. Galuminum = 30GPa; Gbrass = 40GPa.
Determine:
a) The values of the torsional stiffness for the rod and the tube
b) The torque transmitted by each
c) The maximum shear stress in each
d) The angle of twist
