About This Product
Students balance the rod on its pivot, hang weights at different holes on each side and record force and distance to check that the turning moments balance. Moving the load, effort and fulcrum also shows how the three classes of lever give different mechanical advantage. Enquiries from Afghanistan, Mexico, Belarus, Libya, Croatia and Moldova for the Rod for levers receive an export quotation.
Frequently Asked Questions
How long is the Rod for Levers?
It is approximately 38 cm long.
How is the principle of moments checked with it?
Weights are hung at different holes on both sides of the pivot until the rod balances, and force multiplied by distance from the fulcrum is compared for each side.
