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.)

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.

A fender is mounted on a automobile though dampers (to absorb collision energy) and springs (so that the fender can recover after low-speed collisions). During a crash-test, the automobile is moving at 2 m/s when its fender strikes a concrete barrier. The vehicle mass, m, is 1,000 kg. (In comparison, the fender itself is essentially massless.) The springs that mount the fender have a stiffness, k, of 1,000,000 N/m. y m barrier 1) Write a differential equation for the deflection of the springs when the fender is in contact with the barrier. 2) If the damping coefficient, c, is 30,000 N-s/m, what is the damping ratio of the mass-spring-damper system when the fender is in contact with the barrier? 3) For that damping coefficient, make a reasonably accurate sketch (with properly labeled axes) of the time-course of the force exerted on the barrier, starting from the moment of first contact. 4) Is there any value of the damping coefficient, c, that would yield no rebound of the vehicle from…
