homogeneous cylindrical elements

Shaft AB consists of n homogeneous cylindrical elements, which can be solid or hollow. Its end A is fixed, while its end B is free, and it is subjected to the loading shown. The length of element i is denoted by Li, its outer diameter by ODi, its inner diameter by IDi, its modulus of rigidity by Gi, and the torque applied to its right end by Ti, the magnitude Ti of this torque being assumed to be positive if Ti is counterclockwise from end B and negative otherwise. (Note that IDi = 0 if the element is solid.) (a) Write a computer program that can be used to determine the maximum shearing stress in each element, the angle of twist of each element, and the angle of twist of the entire shaft. (b) Use this program to solve Probs. 3.35, 3.36, and 3.38.

Probs. 3.35

The electric motor exerts a 500 N.m-torque on the aluminum shaft ABCD when it is rotating at a constant speed. Knowing that G = 27 GPa and that the torques exerted on pulleys B and C are as shown, determine the angle of twist between (a) B and C, (b) B and D.

Probs. 3.36

The torques shown are exerted on pulleys A and B. Knowing that the shafts are solid and made of steel (G = 77.2 GPa), determine the angle of twist between (a) A and B, (b) A and C.

Probs. 3.38

The aluminum rod AB (G = 27 GPa) is bonded to the brass rod BD (G = 39 GPa). Knowing that portion CD of the brass rod is hollow and has an inner diameter of 40 mm, determine the angle of twist at A.
