a. Calculate the contact pressure at the interface.b. Calculate and plot the radial and hoop stresses in the shaŌ as a funcƟon of radius. Tabulate the magnitude and locaƟon of the maximum/minimum stresses.c. Calculate and plot the radial and hoop stresses in the hub as a funcƟon of radius. Tabulate the magnitude and locaƟon of the maximum/minimum stresses.d. If shrink-fit the shaŌ by liquid nitrogen is intended, what will be the temperature drop needed? Is this achievable? [At normal atmospheric pressure, temperature of liquid nitrogen is ~-320°F).]
