MOMENTS OF INERTIA AND CENTERS OF GRAVITY OF THE LIVING HUMAN BODY ENCUMBERED BY A FULL-PRESSURE SUIT

Abstract

The center of gravity and the moments of inertia of each of 19 male subjects, representative in stature and weight of the U. S. Air Force population, were determined. Two body positions: sitting and relaxed; and three modes of dress: nude, suited-unpressurized, and suited pressurized were investigated. The theoretical accuracy of the experimental procedures, based on a compound pendulum, ranged from 2 to 8 percent, depending on body position and axis. The moments of inertia were found to vary significantly between body positions and between nude and suited conditions. Correlation coefficients between the moments of inertia and stature and weight exceeded 0.9. Fifty anthropometric dimensions and frontal and profile photographs were obtained on each subject to serve as the basis for additional biodynamic analyses.
