A hand cranking lever, as shown in Figure 6 below, is used to start a truck engine by applying a force F = 400 N. The material of the cranking lever has a yield strength = 320 MPa; Ultimate tensile strength = 500 MPa; Young’s modulus = 205 GPa; Modulus of rigidity = 84 GPa and poisson’s ratio = 0.3. Assuming factor of safety to be 4 based on yield strength, design the diameter of the lever at section X-X near the guide bush using: a) Maximum distortion energy theory; and b) Maximum shear stress theory

Question
A hand cranking lever, as shown in Figure 6 below, is used to start a truck engine by
applying a force F = 400 N. The material of the cranking lever has a yield strength = 320 MPa;
Ultimate tensile strength = 500 MPa; Young’s modulus = 205 GPa; Modulus of rigidity = 84 GPa
and poisson’s ratio = 0.3. Assuming factor of safety to be 4 based on yield strength, design the
diameter of the lever at section X-X near the guide bush using: a) Maximum distortion energy
theory; and b) Maximum shear stress theory.
