An athlete begins with the arm in a relaxed upright position OA, in which the elastic band is not stretched. Then he performs an abduction movement leaving his arm in the horizontal OB position. The elastic modulus of the band is 80.0 N / m, that is, 80.0 N of force is required to stretch the band for each additional meter of elongation. If the entire limb has a mass of 2.50 kg and its center of mass is located 250 mm from the shoulder joint. Determine the magnitude and direction of the moment of force with respect to the shoulder joint
