Answer to Question #343439 in Mechanical Engineering for shahab

Question

The disc shown in the figure is supported by two

circular tubes of same cross section and different

lengths which both are connected to the disk at one

end and fixed to a wall at the other end. The internal

and external diameters of the tubes are8cmiD =

and10cmoD = , respectively. Calculate the angle

by which the disk rotates when subjected to a

torque of3kN.mT = . The tubes are made of steel

with Young’s modulus of200GPaE = and

Poisson’s ratio of0.3
