| PULLEY DEMONSTRATION SET ADVANCED
(0103) |
A highly versatile apparatus designed to complement demonstrations of simple machines, force, mechanical equilibrium and almost every physical concept associated with pulleys and their configurations. Right from the wheel of bicycle to the gears in car, it helps explain how things work. It also makes the students understand the concepts such as how an increase in the number of pulleys decreases the force required to lift an object but increases the amount of string that must be pulled, yet the amount of work done being independent of the number of pulleys. Special features include Stable Base: Rectangular wooden base with non-skid feet has a socket near its each end for vertically mounting two threaded metal rods about 81 cm long. Also includes an eye hook and capstan for demonstrating an entire pulley system. Comprehensive: Contains almost everything needed to effectively display almost every conceivable pulley demonstration and their usefulness, including the slotted masses and mass hangers required for the purpose. Also includes two right angle clamps for supporting horizontal rod at the top of vertical rods, collars with hooks for use on horizontal rod for suspending pulleys. Comes neatly packed in a suitable cardboard box. Several Pulley Types: Explore the benefits of single pulleys, sheave pulleys and those of tandem pulleys, quadruple pulleys and even 4-step pulley (wheel & axle): or form different combinations of several of them for an efficient pulley system.
