A hand cranking lever, as shown in Figure 6 below, is used to start a truck engine byapplying 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 GPaand poisson’s ratio = 0.3. Assuming factor of safety to be 4 based on yield strength, design thediameter of the lever at section X-X near the guide bush using: a) Maximum distortion energytheory; and b) Maximum shear stress theory.
