₂20 cm The pinion (small gear) A (with radius 10 cm) of a hoist motor drives a larger gear B (of radius 20 cm), which is attached to a hoisting drum. The load Lis attached to an inextensible cord that wraps around the drum (with radius 30 cm). What is the required angular velocity of the pinion A to lift the load L with a constant velocity of 1 m/s upwards?
