Double Pulley
Product Code : JL-LEP-10159
The Double Pulley (SKU JL-LEP-10159) is used to demonstrate the efficiency of pulley combinations. Rigged with string, a hooked mass as the load and a spring balance on the effort side, the double pulley lets students compare the force needed to raise a load with the load itself, and see how sharing the load between more strands changes the effort. JaincoLab manufactures it in India for school physics laboratories, made as per DepEd guidelines, as part of its simple machines apparatus.
Specifications
The Double Pulley is specified by its purpose in the simple machines set: it is a double pulley for demonstrating the efficiency of pulley combinations, made as per DepEd guidelines and listed under SKU JL-LEP-10159 for ordering with the single pulley, masses and spring balance.

Applications of the double pulley
The double pulley is used in lessons where students build pulley systems, lift a known load and measure the effort, so that mechanical advantage and efficiency can be worked out from real readings. Typical uses are:
- Setting up a pulley combination with the single pulley and thick string
- Lifting a 250 gram or 500 gram hooked mass and reading the effort on a spring balance
- Comparing effort with load to discuss mechanical advantage
- Estimating the efficiency of a pulley system from load, effort and distances moved
Scope of supply and ordering
Each unit is one double pulley, as set out in the specification table. String, hooked masses, the single pulley and spring balances are separate catalogue items; accessories, spares and quantities are confirmed on the quotation.
Minimum order quantity, packing and lead time for the double pulley are quoted to match the number of units and the delivery point. JaincoLab supplies single school laboratories, bulk orders for colleges and education programmes, and export shipments to Africa, the Middle East and South and South-East Asia.
