An exerciser begins with his arm in the relaxed vertical position OA, at which the elastic band is unstretched. He then rotates his arm to the horizontal position OB. The elastic modulus of the band is k=60 N/m-that is, 60N of force is required to stretch the band each additional meter of elongation. Determine the moment about O of the force which the band exerts on the hand B. 635 mm- B F 740 mm
