Question
b) A shaft consists of three-disks attached on the shaft as illustrated in Figure 5. The shaft is fixed
at A and free to rotate in a bearing at its right end at E. Three-disks are located at B, C and D.
The modulus of rigidity (G) for the shaft is 80 (Pa.
Note: Shows all the assumptions and diagrams.
i) Determine the torque that occurs on each segment of the shaft. Draw the torque diagram.
ii) Calculate the angle of twist of section E relative to the fixed section A.
iii) Calculate the torsional shear stress in each segment of the shaft.
