Problem 8.69

Many of the elements in horizontal-bar exercises can be modeled by representing the gymnast by four segments consisting of arms, torso (including the head), thighs, and lower legs, as shown in Figure P8.15a. Inertial parameters for a particular gymnast are as follows: Segment Mass (kg) Length (m) rcg (m) I (kg m2) Arms 6.87 0.548 0.239 0.205 Torso 33.57 0.601 0.337 1.610 Thighs 14.07 0.374 0.151 0.173 Legs 7.54 0.227 0.164 Note that in Figure P8.15a rcg is the distance to the center of gravity measured from the joint closest to the bar and the masses for the arms, thighs, and legs include both appendages. I is the moment of inertia of each segment about its center of gravity. Determine the distance from the bar to the center of gravity of the gymnast for the two positions shown in Figures P8.15b and P8.15c.

Notes from Unit 1: Night Sky: Constellations – combinations of stars ­ Originally used by Mesopotamians, adopted and renamed by Greeks ­ 88 catalogued constellations ­ Where they are in the sky changes based on the rotation and orbit of the earth, different constellations are visible at different times of year Circumpolar- stars that are always on the visible horizon (from one of the poles at least) Polaris- star at the north celestial pole Celestial sphere- imaginary sphere around the earth Meridian- circle that passes through the celestial poles Celestial equator- perpendicular the meridian, same as earth’s equator but in the celestial sphere Altitude- how high up something appears in the sky Azimuth- which compass direction something appears in the sky RA
