Triple-Parallel Plastic Pulley, 50mm Diameter

This Eisco Labs Triple Plastic Pulley features three parallel pulleys, each 50mm in diameter, mounted on a steel frame with hooks at each end. The inner gap of each pulley measures 4mm, and the overall length is 8.9cm. Triple pulleys are used to demonstrate mechanical advantage and pulley systems in physics experiments. The parallel arrangement allows students to explore how multiple pulleys reduce the force needed to lift a load. Suitable for physics classrooms studying simple machines, force, and work.
