Inertial Balance, Economical

Designed to assist in the clarification of relationship between inertial mass and gravitatiol mass, i.e., mass and weight. Comprises two sheet metal rectangular platforms of size 130x50mm (width x length) supported by means of a pair of spring steel strips about 300mm apart. One of the platforms has 3 holes for suspending up to three cylindrical masses. Can be clamped to the bench top using G-clamp through the other platform (without hole) and is free to oscillate in horizontal plane under the restoring forces of spring steel strip connectors. Includes 3 cylindrical masses, a G-clamp, and nylon cord. After establishing the spring constant of the balance, with any combition of three masses placed into the slots, change in time-periods of oscillation can be observed by placing one mass at a time. Once calibrated, unknown masses may be measured.
