2. With both hands directly in front of the body, a worker twists and lifts the core of a 50-lb roll of paper from a cart on her side and then shifts the roll in the hands and holds it by the sides to position it on a machine, as shown in the Figure. Significant control of the roll is required at the destination of the lift. Also, the worker must crouch at the destination of the lift to support the roll in front of the body, but does not have to twist. The horizontal location of the hands at the origin is 30 in. at the origin. The frequency is 960lifts/2 hours. The worker works for 50 hours per week. a.
