An Oiles SP 800 alloy brass bushing is 1 in long with a 0.875-in dia bore supports a rotating shaft `and operates in a clean environment at 32°F. The allowable wear without loss of function is 0.005 in. The radial load is 100 lbf. The shaft speed is 420 rev/min. Estimate the number of cycles for radial wear to be 0.005 in.
