Abstract

The operation of a mechanical machine may behave differently in various gravitational conditions. We compare the mechanical efficiency of a mass-spring system in three different gravitational conditions, namely hypergravity (2G), normal gravity (1G) and microgravity (0G) through parabolic flight. The simple system consisted of a mass load (18.92 g and 21.97 g) attached between two springs 6.91 N/m which make overall length 410 mm. The mechanical efficiency is justified by the decay of the oscillation amplitude of the attached load. Our result shows that the mechanical efficiency for the simple mass-spring system is better in lower gravitational condition.
