Q.2) A person uses an exercise band with an elastic modulus (spring constant) of 35 lb/ft. They begin the exercise with their arm relaxed in the vertical position (OA), at which point the band is unstretched. The person rotates their arm up to the horizontal position shown, so that their shoulder is at point O and their hand is at point B. Determine the moment exerted by the elastic band on the person's shoulder joint in this position.
