Economical pulley for simple machine experiments.

Economical pulley for simple machine experiments.

Total length of rod and pulley is 10". The pulley has a diameter of 2", and is equipped with a metal low-friction bearing installed. The rod is made of durable aluminum, and the pulley is made of durable plastic.

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.

Ideal for studying collisions in two dimensions, these pucks can be supported on plastic beads or levitated with air from the balloons to reduce friction. Use on any smooth, flat surface. The pucks measure 10 cm in diameter, and one puck is twice the mass of the other two.

Free fall experiments have never been easier!

Accurately measure the velocity of your dynamics cart.

This model shows the internal structure and operating principles of an air cooled two-stroke engine. All parts are aluminum and plastic. Ignition is shown via a small bulb. Carburetor and fuel supply are also sectioned. Hand crank is provided for manual operation. Mounted on a base.
