The apparatus consists of three suspension elements, each with varying stiffness, connected at a single point to form a redundant joint. The upper ends of these suspension members are fixed to a vertical wooden board using a positional tie. A vertical load can be applied to the joint, allowing the use of dial gauges to measure the forces and elongations in the suspension members, as well as their horizontal and vertical displacements. The equipment includes dial gauges with magnetic bases, making it easy to capture precise measurements.

Experimental Objective

Comparison of experimental and theoretical results of forces in the members and the component displacement of the loaded joint D of a three bar suspension system for vertical loads.
