Many aspects of a gymnast's motion can be modeled by representing the gymnast by four segments consisting of arms, torso (including the head), thighs, and lower legs, as in Figure P8.85. Figure P8.85b shows arrows of lengths reg locat- ing the center of gravity of each segment. Use the data below and the coordinate system shown in Figure P8.85b to locate the center of gravity of the gymnast shown in Figure P8.85a. Masses for the arms, thighs, and legs include both appendages. Mass (kg) "eg (m) 0.239 Segment Length (m) 6.87 Arms 0.548 0.337 33.57 Torso 0.601 14.07 0.374 Thighs 0.151 0.227 7.54 Legs 0.350 Thigh O Arm Leg 60° 60° Torso Figure P8.85
