Redundant Joint Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-SML-10080
Jlab Export is a leading Redundant Joint Apparatus Manufacturer,and suppliers in India
Redundant Joint Apparatus (code EL-SML-10080) is a three-bar suspension system in which three spring balances of different stiffness meet at one joint, with their upper ends tied to a vertical wooden board. A vertical load at the joint moves it horizontally and vertically, and those movements are traced on paper. This spring-balance joint rig is made by JLab in Ambala, India.

Solving the Redundant Joint
The loaded joint, labelled D, gives two equilibrium equations but there are three unknown member forces, so the system has one redundant. Consistent deformation supplies the extra condition: if the joint moves by u horizontally and v vertically, each member stretches by the component of that movement along its own line, and its force equals that stretch times its stiffness. Solving these relations with the two equilibrium equations gives the member forces and the joint displacement, which are then set against the spring-balance readings, the dial-gauge elongations and the trace on paper.
Other Suspension, Truss and Gauge Items
- Elastically Coupled Beam Apparatus — three suspension rods coupled through elastic beams at their ends.
- Deflection of Truss Apparatus — detachable springs in the tension members make member deformation visible.
- Dial Gauge — extra magnetic-base dial gauge for more elongation readings.
