Jane carries a heavy object in two different body

positions. If the weight of the object (Fp) is 200N, and the

weight of her upper body (Fw) is 450N. In scenario A, she has an

upright posture. Moment arm Lw = 0.02m, Lp = 0.4m. In

scenario B, she leans forward. Moment arm Lw = 0.25m, Lp =

0.5m. Calculate the total torque generated by Fw and Fp about

the lumbosacral joint in these two scenarios.
