B.Tech (ME) 2011  Advanced Mechanics of Solids  (AMS) Previous year questions

Q.1 Compute the largest value of radial and hoop stress for a rotating disc of internal diameter 150mm and external diameter 300mm. The disc is rotating at 1500 rpm. for the disc material, density ρ = 7000 kg/m3 and v=0.3

Q.2 Prove that thickness of a disc of uniform strength is given by
$\mathrm{ \; t} = t_0 exp\left[\frac{-\rho w^2{r}^2}{2\sigma }\right]$
      Where t₀ is the thickness at r = 0
