NAME______________________________ RECITATION SECTION_________ Problem 1 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 =60N/m. Determine the (a) (5pts) the magnitude of the force which the band exerts on the hand B and (b) (10pts) the moment of this force about O .
