Equilibtium of Torque

This design of the traditional wheel and axle eliminates the usual cumbersome fork and pointed pivot bearings and replaces them with a simple axle and single bearing.The GS-301 has four pulley steps, each with a small hole drilled in the rim for attaching a string. The stainless steel axle is mounted in a ball bearing that is embedded in the center of the molding.The GS-302 is a simpler, more economical design with just two pulley steps. The wheel turns in a lubricated sleeve bearing formed in the wheel itself. String or thread can be attached with tape. Tripod, post and clamp not included, but both may be ordered separately.

Roughly modeling an Earth - Moon system, two spheres can be adjusted on the connecting bar. A simple handle fits in a hole at the CG or in another at the geometrical center. The system balances and spins without wobble only about the CG.

The PASCO Air Supply is exceptionally quiet. Its variable output lets students match the air flow to the experiment.A 2-meter hose is included. By adding the SF-9217 T-Adapter and Hose, the Air Supply can operate 2 PASCO Air Tracks at the same time.

Colored liquid in the leak proof chamber assumes a constant slope at a constant velocity. The 1-cm grid scaled on the side allows the slope to be determined for quantitative investigations of Newton's Second Law.

Easier to use by hand because of its smaller diameter, massive tire, and simple means of hanging and loading, this should be in every classroom to bring precession diagrams to life. Requires a rotating platform (#18750) and suspension line.

The first choice would be to place this on a back-less lab stool, but students can also stand on it with outstretched masses or the bicycle wheel gyroscope (#18700) to internalized ideas of torque and angular momentum.

Following Cavendish's classic design, PASCO's Gravitational Torsion Balance combines features that significantly improve ease of setup, durability of the Torsion Band and the quality of results.Easy Torsion Band Replacement— The PASCO Torsion Band is stiffer and stronger than bands in other units, but the band will break at some time. Attachment clips mounted to the replacement band (one is included with the balance) allow easy band replacement with a screwdriver in less than 10 minutes.A Complete Manual--The Instruction Manual and Experiment Guide contains illustrated instructions for setting up and performing the measurements, plus an explanation of the theory and mathematics necessary to understand the results.

Pulse Glass

Ideal for demonstrating that vapor pressure increases when temperature increases.Two glass bulbs are connected with a glass tube, and contain a colored, volatile liquid. Holding one of the bulbs in your hand causes the evaporation of a portion of the liquid that forces the liquid to the other bulb. Length is 23.5 cm.
