An x axis lies along the foot, with xy = 0 at the forefoot and x = 25 cm at the heel. On each forefoot the downward force is f(mg/2), where fis the fraction of the weight on a foot that is supported by the forefoot. Similarly, on each heel the down- ward force is h(mg/2). The foot (and the person) is in equilib- rium around the center of mass. During pregnancy, the center of mass shifts toward the heels by 41 mm. What percent of the weight shifts toward the heels?

Muscle 2 E Muscle 1 0₁29 1 dM1 dM₂ dw Ow W dDB Ow Hand Dumbbell The figure provides a free body diagram of several forces acting about the elbow joint (E) for an isometric elbow flexion exercise. In this case, the subject is holding a 279 N dumbbell (located dpB = 48 cm from the elbow) in a stationary position. W is the combined weight of the forearm and hand (28 N) and acts through the CG of this system (located dw = 19 cm from the elbow). The forearm is elevated from the horizontal, resulting in a 0w = 74 deg angle between the forearm and line of action of each weight. The force produced by Muscle1 is 964 N (with an angle of pull of 0M1 = 53 deg and an insertion length of dm1 = 5 cm from the elbow). Muscle2 has an angle of pull of 0m2 = 24 deg and an insertion length of dm2 = 8 cm from the elbow. What is the force magnitude of Muscle2 required to keep the elbow in a stationary position? You are allowed a 5% margin of error for rounding.
