SD-1.51 – Wheel and Differential Axle Apparatus

A wheel is attached to a differential axle assembly of Ø114mm (major axle) and Ø38mm (minor axle). The wheel and differential axle are secured to a shaft that runs in bearings within a sturdy wall mounting bracket.

Description

A wheel is attached to a differential axle assembly of Ø114mm (major axle) and Ø38mm (minor axle). The wheel and differential axle are secured to a shaft that runs in bearings within a sturdy wall mounting bracket.

All necessary cords, load hangers and weights are provided.

Three pulleys are fixed together to form a compound pulley. A single cord is attached to the wheel and wrapped around a number of times before hanging vertically and ending in a loop for the ‘LOAD’ hanger. A second cord is attached between the major and minor axles. The cord is wrapped in differing directions onto each axle, this direction can be changed for different parts of the experiments. A special hanger (EFFORT) is mounted to the cord of the axles that allows vertical suspension whilst the axles rotate.
