Question

Question 2: An internal combustion engine has a cast iron flywheel that could be considered as a uniform thin disc. This flywheel was found to yield when it rotates with a speed of 9129 RPM. Determine the maximum stress that would be induced in this disc if a maximum permissible speed of 6054 RPM was allowed (elastic deformation). Assume the following properties for the cast iron: $\rho$ = 7180 kg/m$^3$, $\sigma_Y$ = 200 MPa and $\nu$ = 0.25.
