This package of plastic pulleys contains 25 each of 20, 30 and 40 mm diameter pulleys with 3.2 mm bores and one 10 mm pulley with a push fit to a 2 mm motor shaft.
Teach your students about gear ratios and different gear configurations and how these concepts are used to change the amount of applied force to an object.
Smooth-running ball-bearing clamp pulley for use with inclined planes, force experiments, or demonstrations of work and machines, this durable, lightweight plastic pulley fastens to surfaces up to 18 mm thick.
Versatile teaching kit contains enough materials for the whole classroom to learn about and experiment with a variety of pulley configurations. Because these activities are hands-on, students get a real feel for the forces at work.
