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 3.40 kN is supplied by the motor pinion A to the drum gear normal to the contacting surfaces at B, calculate the average offset x of the center of mass G of the sand from the vertical centerline. Neglect all friction in the supporting rollers. Assume r = 145 mm, R = 550 mm, 0 = 18° Detail of contact at B A- B R Answer: X= i mm A large symmetrical drum for drying sand is operated by the geared motor drive shown.
