Electric Motor Clutch 5 in 30 in 1750 rpm 16 in Drum 3 in 1.5 in Figure P3-11. Figure for Problem 3-11. 20 in 3-11. Figure P3-11 shows a drum that is driven by a 1750 rpm induction motor through a clutch and gear pair coupling. Assume that the materials are steel and that the drum is accelerated from rest to full-load speed in 1 second. What clutching torque will be required to do this? You can neglect the rotary inertia of the clutch.
