Experiment: Balancing out twisting effects
This really simple experiment shows how twisting effects are generated and how they balance out.
It’s another example of equilibrium – simple, elegant and surprisingly accurate.
If you haven’t given the other experiments a go, why not try these?

Talking points
The balancing experiment has some hidden features.
- The cardboard is pinned in its centre. What influence does its weight have on the balance condition?
- How does the vertical distance between the centre hole and the holes for the hangers influence the sensitivity of the system?
- What do you think of the precision that can be obtained from this simple balance?
