A large symmetrical drum for drying sand is operated by the geared motor drive shown. If the mass of the sand is 710 kg and an average gear-tooth force of 3.10 kN is supplied by the motor pinion A to the drum gear normal to the contacting surfaces at B, calculate the average offset of the center of mass G of the sand from the vertical centerline. Neglect all friction in the supporting rollers. Assume r = 155 mm, R = 530 mm, 0 = 18% Detail of contact at B 227 Answer: x = i B R mm
