man is holding a 3.6-kg sphere in his hand with the entire arm held horizontally as shown in the figure. tensile force in the deltoid muscle prevents the arm from rotating about the shoulder joint O; this force acts at the angle shown. Determine the force exerted by the deltoid muscle on the upper arm at A and the x- and y-components of the force reaction at the shoulder joint O. The mass of the upper anm is (m,-1.9 kg), the mass of the lower am is (m-1.1 kg), and the mass of the hand is (my-0.4 kg); all the corresponding weights act at the locations shown in the figure. Group A X-2 mm Group B XI4 mm Group C X=6 mm

In Figure 9.21, the cg of the pole held by the pole vaulter is 2.00 m from the left hand, and the hands are 0.700 m apart. Calculate the force exerted by (a) his right hand and (b) his left hand. (c) If each hand supports half the weight of the pole in Figure 9.19, show that the second condition for equilibrium (net =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 9.21 A pole vaulter is holding a pole horizontally with both hands. The center of gravity is to the left side of the vaulter.
