A fast and effective method to evaluate the strength of trusses.

Air Strike™ desktop catapult can launch the included foam balls as far as 40 feet. Simple to assemble, no tools required. Features super grip suction cups and a pivoting launch base.

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.

Measuring apparatus for investigating the elastic deformation of rods of flat geometry and for determining the modulus of elasticity.

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

A set of 15 samples of different materials used to challenge students to identify materials based on measurement of their density. For some specimens this will be straightforward. In other cases, it will lead to a discussion of uncertainty in measurements and data, and to an awareness that different materials may have nearly the same density.

Launch an egg and test recovery systems with this reliable, sturdy model rocket.

Reliable, quantitative data over Bluetooth to investigate important concepts in projectile motion.

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.

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

We all wish we had our own hybrid automobile to take apart, re-purpose, and use to show others exactly how this fascinating piece of technology works. Just because this may not be a possibility for you doesn't mean you can communicate the basics of hybrid technology.

The Porta pad E launch system is large enough to accomodate those rockets that require larger, 24 mm E and F engines. It has a larger footprint for added stability and a larger blast deflector plate. The Porta pad E comes with the larger ³/₁₆" Maxi launch rod.

This product is a model of a wankel engine. The transparent plastic housing enables the students to see the internal structure at all angles. The rotor starts moving when the switch is turned on. It is powered by 110V AC. 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: Size: 15L x 20W x 28H cm ; Weight: 3 kg

Most people are familiar with the key factors of hybrid technology: The engine and motor. However, most don't get a chance to peek inside of these key components while they're running to examine, assess, and diagnose.

A set of dynamic cart trolleys are used for investigation on momentum, velocity and acceleration. Each trolley consists of two rectangular wooden blocks, 300 mm long, moving on three low friction wheels (ball bearings in wheels). The trolley is fitted with spring loaded impulse rod. It has a provision for stacking the trolleys on top of each other with removable pins. It is supplied with two rubber corks and 2 needles, so trolleys may be stuck together for inelastic collisions. A striking pin for releasing the striker and 3 pins or dowels for stacking are provided. One trolley weight approximately 1 kg.

Use the Time of Flight Pad to precisely measure how long a projectile has been in motion. The Time of Flight Pad is used with the Vernier Projectile Launcher and a Vernier interface to determine the launch speed of a projectile, along with the time the projectile is in flight. Time-of-flight measurements allow students to see just how kinematic calculations work in real-world applications. The Time of Flight Pad is electrically like a photogate. When a ball strikes the foam top surface, a circuit is closed.
