Answer: 1.09 m
Explanation:
Given
Weight of the body, W1 = 496 N
Weight of his upper legs, W2 = 199 N
Weight of his lower legs, W3 = 81.2 N
Center of gravity of the body, y1 = 1.37 m
Center of gravity of the upper legs, y2 = 0.711 m
Center of gravity of the lower legs, y3 = 0.284 m
Center of gravity relative to the floor, y(f) = ?
y(f) = (W1y1 + W2y2 + W3y3) / (W1 + W2 + W3), substituting the values, we have
y(f) = [(496 * 1.37) + (199 * 0.711) + (81.2 * 0.284)] / (496 + 199 + 81.2)
y(f) = (679.52 + 141.489 + 23.0608) / 776.2
y(f) = 844.0698 / 776.2
y(f) = 1.09 m
