Rigidity Apparatus (Searle's Pattern) Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-11958
Quick Answer: The Rigidity Apparatus (Searle’s Pattern) measures the modulus of rigidity of a wire by the dynamic method, with two identical 300 mm brass frames joined by the specimen wire. Two solid and two hollow brass cylinders change the moment of inertia.
Last updated: October 2026
Key Features
- Two identical brass frames, 300 mm (30 cm) each
- Frames joined by the specimen wire, held in clamping chucks
- Two solid and two hollow brass cylinders of matched size
- Cylinders change the inertia between runs
Technical Specifications
| Specification | Value |
|---|---|
| Frames | Two, brass, 300 mm each |
| Connection | Specimen wire in hardened clamping chucks |
| Inertia masses | Two solid and two hollow brass cylinders |
| Method | Dynamic torsional oscillation |
About This Product
The two frames are set swinging in opposite directions, twisting the wire between them, and the period is timed first with the solid cylinders and then with the hollow ones. Comparing the periods with the known masses and sizes gives the modulus of rigidity of the wire.
