About This Product
The rod is set level on its pivot with the trim screws, slotted masses are hung from the stirrups, and their distances from the fulcrum are read off the scale. Students adjust loads and distances until the beam settles level and compare the moments on each side. Moving the fulcrum and the points of effort and load shows class 1, class 2 and class 3 levers. The Rod for lever with stand can be supplied on export terms to Rwanda, Zimbabwe, Cameroon, Fiji and Grenada.
Frequently Asked Questions
Can the Rod for Lever with Stand show all three classes of lever?
