"3B torso model"

Ensure perfect geometric alignment of your balsa fins on any Estes model rocket.

The Digital Photogate Free Fall Apparatus retains the precision of older models while eliminating the hassle of setting up heavy steel columns and adjusting spark recorders.

A simpler version of the Advanced Pulley Demonstration Set, this model includes eight single pulleys and two double sheave pulleys in addition to EISCO ball bearing frictionless pulley.

Investigate and experiment with 7 functioning Wheel & Axle and Inclined Plane models designed to demonstrate science and technology concepts.

Students can determine, through investigation, if the machine multiplies the force it applies to the resistance (load), if the machine changes the direction of the force they apply, and more.

This product is a small-sized model unit used for explaining the principle of a planetary gear. By setting the internal sun and pinion gears into motion (input or fixed), you can get the different outputs from acceleration, deceleration and reverse. Comes equipped with a storage case holding 10 Planetary Gear Demonstrators. These items are made special to order and are not held in stock. Lead times are approximately two to three months. Freight charges may apply. Dimentions: 24L x 14W x 14H cm ; Weight: 3kg

Useful for collision and pendulum experiments.

Experiment topics:
• Rotary oscillations
• Determination of moments of inertia using the oscillation method
• Moments of inertia of various geometric bodies
• Steiner's theorem

Torsion of Metal Rods Apparatus shows students the affect of a torque on a metal rod.

Great for studying the simple harmonic motion of a torsional pendulum.

A Great Classroom Solution.

The Moment of Force Apparatus contains everything needed to study principles of mass, levers, moments, forces, and equivalence.

Gravitational Torsion Balance and He–Ne–Laser demonstrates gravitational attraction between two bodies and determines the gravitational constant.

This balance is the first major advancement in teaching simple machines in decades.

Add your own lab materials to illustrate torque.

Pulley with metal clamp attached.

Plastic pulley with metal clamp, includes knob for tightening.
