Economical pulley for simple machine experiments.

With the Large Plastic Dynamics Cart, students can explore the changes in motion that occur in a dynamics cart when different amounts of net force are applied.

Uses torsion spring bundles and levers to launch ping pong balls.

Economical pulley for simple machine experiments.

This inclined plane is as straight as an arrow, measures a full 4' long, and will last for years. Is built of nickle-plated heavy steel with rounded corners, and can accomondate just about any kind of cart you choose.

Consists of two interconnected cylinders of different diameters based upon two graduated glass syringes of 10mL and 50mL, with cross-sectional area of 3 to 1.

Study the motion and behavior of gas molecules with this intriguing demonstration. An electric motor, running at 4 to 12 V DC, vibrates a small platform inside a transparent tube. This platform then violently vibrates the many small stainless steel balls inside the tube.

Studying dynamic tension has never been easier with this simple form truss kit. The kit includes a half-meter truss with hooks on both sides, V-shaped clamp.Recommended stand and rod, item 470137-892 Required but not included are masses and spring scale.

This pulley is ideal for use with photogates sensors. Pulley is mounted on free-running ball bearings with minimum friction. Mounted on a removeable rod of 150 x 10 mm diameter.
Diameter 65 mm with spokes
Ideal for use with Photogates

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.

A classic and fun demonstration.

Individual design kit for pinewood racing.

Gears are so much a part of everyday life that it would be easy to overlook their impact.
