A steel shaft rotates in a close-fitting polymeric bearing of hardness (50N/mm²) at a constant speed of (20 rev/min). The effective wear coefficient (K) is 102. Calculate the length of the bearing required to ensure that the radial penetration of the shaft into the bearing does not exceed (5 mm) in a running period of (500 hours) when the load is (10N).

Question
A steel shaft rotates in a close-fitting polymeric bearing of hardness (50N/mm?) at a constant speed
of (20 rev/min). The effective wear coefficient (K) is 102. Calculate the length of the bearing
required to ensure that the radial penetration of the shaft into the bearing does not exceed (5 mm)
in a running period of (500 hours) when the load is (10N).
