EF-2.3 – Dynamics - Rotational Friction

The EF-2.3- Rotational Friction experiments kit enables students to understand how rotational friction affects the efficiency of a screw jack, a wedge and different bearings

The kit includes experiments that measure the effort required to raise various loads using a simple form of screw jack.
These include determining how the mechanical advantage and efficiency varies with load, the mechanical advantage and efficiency obtained by using two different wedges including investigating the effect of the angle on overhauling and to compare the resistance to rotation due to friction in four cantilevered bearings of different materials.
