Apparatus consists of three suspension members (spring balances) of different stiffness, which are jointed at a point to form the redundant joint. The upper end of the suspension members being tied in a position to a vertical wooden board. Arrangement is provided to apply a vertical load at the joint and to measure its horizontal and vertical displacement on a paper and also elongations and forces in the suspension members by the help of dial gauges. Dial gauges with magnetic base are provided with the apparatus.

Experiment:

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.

Required Accessories:

• Redundant Joint Apparatus
• Dial Gauge: 1 No.
• Magnetic Base: 1 No.
• Hangers: 1 Nos.
• Weight of 500gm: As Per requirement.
