An architecture student working at a drafting table requires some muscle action in order to support her head. As shown in the figure, three forces act on her head. If the force provided by muscles is F, = 70 N and the weight of her head is W = 40 N, determine the magnitude and direction of the force provided by the upper vertebrae F, to hold her head stationary. Assume that this force acts along a line through the center of mass of her head as do the weight and muscle force. (Assume the +x-axis to be to the right.) magnitude direction • measured clockwise from the -x-axis W
