GP-215.1 LINEAR AIR TRACK Designed for the study of linear motion under conditions of low friction, is made from strong, square section aluminium. Two rows of fine holes run along the top of the track through which jets of air emerge to or an air cushion on which the vehicles float under virtually frictionless conditions. The track is supported one five adjustable feet. An air inlet tube connection is fitted at one end and a butterfly valve at the other by means of which the air pressure inside the track may be adjusted. The track is supplied complete with the following accessories : (a) Two heavy and one light vehicle, their masses in the ratio 2:1 with a tolerance of ± 2%. (b) Two metal location plates drilled to take the inner feet of the track so that it can be firmly positioned on the bench using ‘G’ clamps, screw of self adhesive pads. The plates are fitted with pegs to support the shutter accessory pillars. (c) Three moulded black ‘buffers’ and three ‘horns’. (d) One set of pin and absorber (Plasticine) attachments for work on in elastic collisions. (e) A supply of self-adhesive buffers for an alternative method with inelastic collisions. (f) A set of Magnadur magnets (2) and counter balances (2) for work on collisions at a distance. (g) Ten spare rubber bands. (h) Three black cards to fit the vehicles for use in timing. (i) 4 elastic chords with plastic ring on each end. (l) Reel of nylon thread. SPECIFICATION Track Square section aluminium 50x50mm, overall length 2m. Vechicles two of 230mm approx.x50x6mm, One of 215mm approx. x 50 x3mm.  GP-215.2 ELECTRIC BLOWER For use with the Air track and Air Table. consisting of a 240V, industrial type vacuum cleaner(used with the hose connected to the outlet) which is capable of providing a high rate of airflow and a maximum pressure of 14kPa approximately. The blower is supplied complete with a wide bore air hose 1.7m long, hose adaptor and 2-core captive mains lead. The motor and other electrical parts are fully insulated. Mains operated electronic linear reads 0 to 99.99sec. The display comprise 4 seven segment digits to read seconds and centi-seconds. Two pair of 4mm sockets with two pushbutton switches are controlled with switches which enable linear make or break pulses to be used to operate the timer. A reset is provided to the base. Dimensions: Overall length without pulley 550mm approximately, width 150mm.  GP-215.3 PHOTOGATES It is used as a light up erated timing gate. It consists of a photo detector and light source (2.5V, 0.2A) housed in two plastic cases held 40mm a part on a metal rod. 4mm sockets are provided for connecting it to the electronic timer, power 2V AC. Two sets are required with one linear air track. One to start timer other to stop the timer. Page : 1 |
