Cable Statics Apparatus for Point and Distributed Loads
集中与分布荷载索静力学试验装置
Before tackling suspension bridges, students need to see how a free cable takes the shape of its loading. This backboard rig spans 1000 mm with supports up to 200 mm apart in level and a 1.5 mm steel wire. Up to six 30 N point loads or a chain for catenary shape are applied, with 0–100 N spring balances reading end tension and a 1 mm scale for sag.
- Span
- 1000 mm, supports at adjustable heights
- Cable
- Flexible steel wire, 1.5 mm
- Support levels
- 0 to 200 mm difference
- Point loads
- Up to 6 hangers, 0–30 N each
- Distributed load
- Chain loading for catenary shape
