Question

Calculate the torque T:

i. if the shear stress of the brass sleeve in section AB is limited to τb = 70 MPa.
ii. if the shear stress of the steel shaft in section BC is limited to τs = 110 MPa.

Brass sleeve d: = 90mm di = 70mm Steel shaft T B I = 200mm I- 200mm Figure 1: A compound of shaft consisting brass sleeve and steel shaft.
Transcribed Image Text:Brass sleeve d: = 90mm di = 70mm Steel shaft T B I = 200mm I- 200mm Figure 1: A compound of shaft consisting brass sleeve and steel shaft.
A composite shaft consists of a brass sleeve securely bonded to half steel shaft, fixed at end A as shown in Figure 1. The brass sleeve and steel shaft have a modulus rigidity Gs = 40 GPa and G. = x0 GPa. The length of the assembly is L = 400 mm. The outer diameters of the shaft and sleeve are di = 70 mm and d = 90 mm, respectively. Given the shear stress of brass is th= 70 MPa and shear stress of steel is t,= 110 MPa. [Note: x value - Use the last non-zero digit from your matric number. If the number is zero, use the second last digit instead. For example, if your matric number is B051810204, your x value is 4 and G, = 40 GPa; if your matric number is B051810090, your x value is 9 and G, = 90 GPa.]
