Assume you are given a spherical joint where the ball has a radius of 20 mm and socket has a radius of 22 mm. If the contact load is 50 N, E = 210 GPa, and ν = 0.3, determine (a) the radius of the contact area, (b) the maximum contact pressure.
If the maximum temperature in the cycle is not to exceed 2200 K, determine the thermal efficiency and the mean effective pressure.
A long electric wire of radius r0 generates heat at rate of q'''. The surface is maintained at uniform temp of T0. Write heat equation and boundary conditions for steady state one dimensional conduction.
