The figure 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 stationary. To pull the arm downward, the latissimus dorsi muscle applies the force in the figure, at a point that is 0.069 m from the shoulder joint and oriented at an angle of 29º. The arm has a weight of 43 N and a center of gravity (cg) that is located 0.28 m from the shoulder joint. Find the magnitude of M. Axis at houlder joint 29 0.28 m 0.069 m 0.61 m 98 N

Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.
