A heavy-duty sleeve bearing is used with good ventilation. The bearing has a diameter of 2 in. and a length of 4 in. The load on the bearing is 1100 lb. A shaft rotates 200 rpm in the bearing and does not transmit any heat to the bearing other than that due to shaft-bearing friction. The coefficient of friction is 0.02 and the ambient temperature is 70 F. Find the probable operating temperature of the bearing. A. 141.75 F B. 174.34 F C. 141.23 F D. 131.50 F A heavy-duty sleeve bearing is used with good ventilation. The bearing has a diameter of 2 in. and a length of 4 in.
