- In the figure below, the cg of the pole held by the pole vaulter is 2.54 m from the left hand, and the hands are 0.733 m apart. Assume the vaulting pole has a mass of 3.32 kg.) (a) calculate the force (in N) exerted by his right hand ( enter the magnitude.) (b) calculate the force (in N) exerted by his left hand. ( enter the magnitude) (c) If each hand supports half the weight of the pole in the figure below , show that the second condition for equilibrium (net τ = 0) is satisfied for a pivot other than the one located at the center of gravity of the pole. Explicitly show how you follow the steps in the Problem-Solving Strategy for static equilibrium described above. Figure C is the last diagramPlease help meConsider the following. (a) What is the mechanical advantage of a wheelbarrow, such as the one shown in the figure, if the center of gravity of the wheelbarrow and its load has a perpendicular lever arm of 6.70 cm, while the handles have a perpendicular lever arm of 1.06 m? 15.820 (b) What upward force must you exert to support the wheelbarrow and its load if their combined mass is 57.5 kg? 35.617 (c) What force does the wheel exert on the ground? (Indicate the direction with the sign of your answer. Assume the positive direction points upward.) 527.85
