| The drawing shows an outstretched arm (0.61 m in length) that is parallel to the floor. The arm is pulling downward against the ring attached to the pulley system, in order to hold the 98-N weight *75. stationary. To pull the arm downward, the latissimus dorsi muscle applies the force M in the drawing, at a point that is 0.069 m from the shoulder joint and oriented at an angle of 29°. The arm has a weight of 47 N and a center of gravity (cg) that is located 0.28 m from the shoulder joint. Find the magnitude of M. 0.61 m 0.28 m 0.069 m Axis at 98 N shoulder joint cg 29
