Question:

Because of wearing at the edges, the pivot bearing is subjected to a conical pressure distribution at its surface of contact. Determine the torque M required to overcome friction and turn the shaft, which supports an axial force P. The coefficient of static friction is μs. For the solution, it is necessary to determine the peak pressure p0 in terms of P and the bearing radius R.
