Wheel And Axle, On Stand

Product Code : LSK-AM-11107

Wheel And Axle, On Stand (SKU LSK-AM-11107) is a simple-machine demonstrator made of two grooved, polished wooden wheels of 12 cm and 7.5 cm diameter fixed rigidly together and turning on steel centres above a wooden base. A small effort on the larger wheel raises a heavier load on the smaller one. Science Lab Supplies produces this model in its own Ambala workshop at Plot 448, HSIIDC Industrial Area, Saha, India, for direct supply to schools, polytechnics, tender contractors and distributors.

Specifications

Every specification of the model is listed in the table below. Put simply, a 12 cm wheel and a 7.5 cm wheel, both of polished wood with grooved rims, are joined as one rigid unit on steel centres over a wooden base and supplied with cord and hooks, while weights are ordered separately.

Applications and Experiments for the Wheel and Axle

The model is used to find the mechanical advantage, velocity ratio and efficiency of a wheel and axle. Effort hangs from a cord wound on the 12 cm wheel and the load from a cord on the 7.5 cm wheel, so the ideal velocity ratio is 1.6 and friction losses can be measured.

• ICSE Class 10 machines: comparing load and effort to calculate mechanical advantage, velocity ratio and efficiency.
• Class 9–10 general science: showing how a larger wheel lets a smaller force lift a heavier load, with loads from Weights with Hooks.
• Diploma applied mechanics: plotting effort against load and finding the law of the machine, with the effort side read on a Set of Spring Force Meters.

Wind the two cords in opposite directions so that one unwinds as the other winds up, and increase loads gradually. Finer load steps can be built from the Physical Weight Box Of 100gm Iron Chrome Plate.

Standard Scope of Supply

Each unit consists of the two polished, grooved wooden wheels of 12 cm and 7.5 cm diameter fixed together on steel centres, the wooden base, and the cord and hooks. It is supplied without weights, so load and effort masses should be ordered as separate lines on the quotation.

Packing, MOQ and Lead Time

A quotation can be raised for a single wheel and axle or for a batch covering every bench in a simple-machines practical. It will state the packing, delivery time and price for the quantity requested, and hooked weights or pulleys can be quoted with it.

Because it holds an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. Write to the team using the contact page, build a list in the enquiry cart, or see the lab tender page for institutional tenders.

Frequently Asked Questions

What is the velocity ratio of this wheel and axle?
The wheel diameters are 12 cm and 7.5 cm, so the ideal velocity ratio is 12 divided by 7.5, which is 1.6. The measured mechanical advantage will be lower because of friction.

Are weights included with the apparatus?
No. The wheel and axle comes with cord and hooks but without weights. Hooked weights or slotted masses for the load and effort sides can be added to the same quotation.

What are the wheels made of?
Both wheels are polished wood with grooves for the cord. They are fixed rigidly together so that they turn as one unit on steel centres mounted above a wooden base.

Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the maker. This wheel and axle is built in its factory in Saha, Ambala, India, and quotations are sent out from that factory rather than through a reseller.
