創新系統

The Unit for studying Equilibrium of Moments on a Two Arm Lever, "MEMB2", provides a simple way of understanding experiments on the equilibrium of moments.

一般說明

The Unit for studying Equilibrium of Moments on a Two Arm Lever,"MEMB2", allows to study the fundamentals of the equilibrium of moments and the application of the law of levers on a two-arm lever.

A pivoted beam in the extreme of a vertical support represents a two-arm lever. Several loads can be applied at various positions of the lever with movable riders, weights and weight holders. These loads will make the beam rotate. The equilibrium is attained by moving the loads, and the moment necessary to overcome this rotation and keep the beam level can be determined.

The beam is graduated in each direction from the central pivot to read the distances from the pivot point – the lever arms. The calculation of the lever arms can be verified in the exercises.

Three movable riders are included for applying loads.
