A large symmetrical drum for drying sand is operated by the geared motor drive shown. If the mass of the sand is 780 kg and an average gear-tooth force of 2.20 kN is supplied by the motor pinion A to the drum gear normal to the contacting surfaces at B, calculate the average offset T of the center of mass Gof the sand from the vertical centerline. Neglect all friction in the supporting rollers. Assume r = 140 mm, R = 680 mm, 0 = 18°. Detail of contact at B Answer:I=i mm
