- Pregnancy shift of com. Figure gives a simplified view Forefoot x=0 f(mg/2) com Heel -x h(mg/2) of the weight supported on each foot of someone with weight mg standing upright with half the weight supported by each foot. An x axis lies along the foot, with x = 0 at the forefoot and x = 25 cm at the heel. On each forefoot the downward force is f(mg/2), where f is 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? (The center of mass shifts back to its initial position after pregnancy.)C Dynamic Analysis and Aeroelasticity SECTION B Answer TWO questions from this section ENG2012-N The moment of inertia of a helicopter's rotor is 320kg. m².
