Design Engineering: Find Specific Load and Heat Generated Per Minute

A load of 6400 Kg is carried by a journal rotating in a 270 mm bearing diameter and 400 mm long. Find the specific load on the bearing and the heat generated per minute in the bearing, assuming the shaft speed is 4 r/s and the coefficient of friction is 0.018.

Solution Preview

Length L = 400 mm = 0.40 m
diameter D = 270 mm = 0.27 m
load W = 6400 kg = 6400*9.8 N
Therefore, specific load
w = W/A = ...
