A light bamboo fishing pole 9 ft long is supported by ahorizontal string as shown in the diagram. A 10 lb. fish hangs fromthe end of the pole, and the pole is pivoted at the bottom. What isthe tension in the supporting string? What are the horizonal andvertical components of the force of the pivot (axis) on the pole?8. The length of the femur (thighbone) of a woman is 38 cm, and theaverage cross section is 10 cm2. How much will the femur becompressed in length if the woman lifts another woman of 68 kg andcarries her piggyback? Assume that, momentarily, all the weightrests on one leg. 9. The “seconds” pendulum in a pendulum clockbuilt for a 19th century astronomical observatory has a period ofexactly 2.0 seconds, so each one-way motion of the pendulum takesexactly 1.0 seconds. What is the length of such a “seconds”pendulum at a place where the acceleration of gravity is 9.79m/s2?
