Wheel and Axle Apparatus
Product Code : EL-AMLE-10642
Wheel and Axle Apparatus (code EL-AMLE-10642) is a wall-mounted model used to demonstrate the conditions of equilibrium on a differential pulley block. Three anodised aluminium pulleys of 250 mm, 100 mm and 75 mm diameter sit on a ball bearing mounted steel shaft; the load acts directly on the largest pulley and, through a 75 mm loose pulley, on the two smaller ones, with 2 sets of interchangeable weights for finding equilibrium.

What Is the Wheel and Axle Apparatus Used For?
A wheel and axle, or differential pulley block, lets a small effort on a large-diameter pulley balance a larger load acting on smaller ones, because the moments of the forces about the shaft must be equal. The student hangs weights on the cord at the 250 mm pulley and on the loose pulley carried by the two smaller pulleys, then adjusts the loads until the system stays at rest. Comparing the loads with the pulley radii checks the equilibrium of forces and moments, and measuring how far each cord moves shows that the force reduction is paid for by greater cord travel.
What to Specify When Ordering
- Quantity — the number of wheel and axle units required.
Frequently Asked Questions
What pulley sizes are fitted?
Three anodised aluminium pulleys of D=250 mm, D=100 mm and D=75 mm are fitted to the shaft, and a separate loose pulley of D=75 mm acts on the two smaller ones.
Which weights are included?
Two sets of weights are supplied, made up of 2 × 1 N hangers with 4 × 0.5 N, 4 × 1 N, 4 × 2 N and 4 × 5 N weights.
What experiments can be performed?
The model is used for experiments on the equilibrium of forces, the equilibrium of moments and the relationship between force reduction and cord travel on a differential pulley block.
How is the model fixed in place?
It is intended for wall mounting on its anodised aluminium base plate of 300 × 250 mm, whose fixing holes are spaced 280 × 230 mm with D=10 mm.
What are the overall size and weight?
The complete apparatus, with its three pulleys and shaft, is 300 × 280 × 250 mm in length, width and height, with a weight of approximately 15 kg.
What should an overseas buyer include in an enquiry?
Give the quantity, the destination country and the port or city of delivery, the delivery terms such as FOB or CIF, how the goods should be packed and, where one applies, the tender reference.
