Multiple pulley Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12648
A Multiple Pulley is an educational physics apparatus used to study the relationship between load, effort, tension, and mechanical advantage. It generally consists of multiple grooved wheels mounted in a frame or block, allowing a string or cord to pass smoothly through the pulley system. By using more than one pulley, students can observe how effort is reduced while lifting a load.
Educational Instrument India Multiple Pulley is designed for easy setup, smooth operation, and repeated laboratory use. It is suitable for experiments on simple machines, work, energy, force transmission, and the efficiency of pulley systems. Teachers can use it for demonstrations, while students can use it for practical observation and calculation-based activities.
