Linear Air Track
Square section aluminium alloy track, length 1.5 m, with staggered holes, supported on two light alloy castings. One support has a two-point contact and other one-point contact for lateral and horizontal adjustments by means of a knurled screw. Identical end caps enable air to be introduced from either end of the track keeping the other end closed.
Linear Air Track Accessories Consisting of
2 Large vehicles (length 180 mm).
1 Small vehicle (length 140 mm).
2 Magnetic buffers (25 mm dia.).
2 Plasticine Holders (20 mm dia.) with central hole.
4 Catapults (45 mm wide) with slots for elastic band.
1 Reel of nylon thread.
2 White rods (4 mm dia. 150 mm long).
24 Needles.
20 Plain cards.
1 Reel rubber strand.
1 Pack of plasticine.
20 Elastic bands.
2 Needles with holder.

Smart Photogate Timer
Photgate timer has been designed to measure the time interval between two photogates. It can measures the time it takes to pass through one photogate, measure acceleration of a released ball, determine the acceleration due to gravity (with a picket fence), determine elastic and inelastic collision times, calculate cycles, determine the period of a pendulum, count interrupts and time with stopwatch with great accuracy. All the results are displayed on a LCD Display. This timer allows you to watch the experiment as it happens and perform calculations easily and accurately. Includes a magnetic ball drop.

Ticker Tape Timer
For measuring velocity and acceleration. A vibrating striker prints dots on the tape using carbon disc. The unit is housed in a sturdy plastic case, works on 6-9 V DC, producing 25 or 40 dots per second. With 38mm carbon discs (12) and tape roll small 15mm x 30 mtr.

Mechanics
Ticker Tape Timer
To provide dots on tape at 1/50 or 1/60 second intervals, equal to the frequency of the mains supply. Operates on 12 V ac. It has an electromagnet and a spring-loaded armature which vibrates above a support table. Paper tape drawn through guides on the table is struck by a dotting screw, carried on the armature. A peg on the table is provided to allow full use of carbon paper disc. Fitted on base with 66mm carbon discs (12) and tape roll small 15mm x 30 mtr.

Battery Powered Acceleration Timer
This battery-powered timer produces 30 to 50 marks per second for dynamic experiments. 1.5V motor operates on two D-cell batteries (not included). Wooden base improves stability, reduces vibration and permits attachment to a ring stand post. Striker mechanism acts against an aluminum plate to produce improved-dot definition on the ticker tape.
43mm disc carbon (12) and small tape roll 15mm width x 30mtr.

Double Cone And Incline
A fascinating demonstration of center-of-gravity principles. When placed on the diverging bars of the inclined plane, the cone appears to roll up the plane. Upon careful examination, students determine that the axis of the cone is actually moving down the slope of the bars.

“G” By Free Fall
The apparatus consists of an electromagnet housed in a plastic case with connections provided for an external timer. It also contains a platform unit containing a switch and terminals for the external timer. The unit is supplied with a heavy steel sphere. With the upper and lower unit connected to the external timer, the sphere is released by moving the switch on the electromagnet to the upward position. This action simultaneously starts the timer. As the sphere hits the cork mat on the platform unit, it activates a switch to turn off the timer.

Apparatus to study the eccentricity of center of gravity
In architectural design, it is recommended that spaces for unusually heavy weights be in basements or in buildings isolated from the main structure. Ductile parallel pipes with a central plumb line, which enable to demonstrate that the center of gravity of solid passes through its support polygon. It is made by positioning the stiff elements asymmetrically with respect to the center of gravity of the story.
