Wheel & Differential Axle Apparatus | ProDynami – 1228
The Wheel & Differential Axle Apparatus ProDynami – 1228 demonstrates equilibrium conditions on a differential pulley block using three anodised aluminium pulleys. This Wheel and Differential Axle Apparatus applies forces directly and via a loose pulley across pulleys of different diameters on a ball bearing mounted steel shaft. Interchangeable weights allow load variation to study force and moment equilibrium. Standard and optional pulley sizes are available for wall mounting.
The Wheel & Differential Axle Apparatus ProDynami – 1228 demonstrates the conditions of equilibrium on a differential pulley block. This Wheel and Differential Axle Apparatus uses three anodised aluminium pulleys of different diameters fitted to a shaft mounted on ball bearings. Forces act directly on the largest pulley’s periphery and via a loose pulley on two smaller pulleys.
Product Overview
The model demonstrates the conditions of equilibrium on a differential pulley block. Three anodised aluminium pulleys of different diameter are fitted to a shaft mounted on ball bearings. The forces act, on the one hand, directly on the peripheral of the largest pulley, on the other hand, via a loose pulley on two smaller pulleys. Easy to interchange weights permit the load to be varied such that equilibrium is obtained on this Wheel and Differential Axle Apparatus. The model is intended for wall mounting.

Construction and Design
The Wheel & Differential Axle Apparatus ProDynami – 1228 is built around three anodised aluminium pulleys of different diameters, fitted to a ball bearing mounted steel shaft. Standard pulley diameters are D=250mm, D=100mm, and D=50mm. Forces act directly on the periphery of the largest pulley, and via a loose pulley on the two smaller pulleys. The base plate is HDF laminated. Interchangeable weights, including 2x 0.5N hangers, 4x 0.5N, 4x 1N, 4x 2N, and 4x 5N, permit the load to be varied so that equilibrium is obtained. Optional pulley diameters of D=190mm, D=114mm, and D=38mm are available, along with an optional loose pulley of D=80mm. The model is intended for wall mounting.
