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? (The center of mass shifts back to its initial position after pregnancy.)

upper leg muscle 9 cm in radius). 2) Don't ever try the acorn diet, its nuts. In the tree diagrammed here, a force of 800 N is exerted at the tip of the limb (equivalent to the weight of "800 apples). The limb is circular in cross-section and 2 m long with a tip radius of 3 cm a base radius of 10 cm. The radius increases linearly from the tip to the base. Plot the tensile stress at the top of the limb along its length. Where along the length would you expect the limb to break? M. X. Lo Y

A 50.0N weight uniform 4 metre long beam is hanging from a cord held out at a 30° angle as shown. And unknown weight not shown in the diagram is also hanging 1 m from the X on the diagram. A) The tension in the cord is measured with a spring balance and found to be 130 N. find the counter clockwise torque from the cord about the X shown in the diagram. B) balance torques to find the torque from the unknown weight that is not shown in the diagram Hint: add the unknown weight to the diagram and do not forget to include the weight of the beam in your calculation
