Triangular section Aluminium alloy track, length 255cm with staggered air holes at 25mm spacing approx,
supported by two light alloy casting positioned 45cm from each end of the track. Each support has an
adjustable knurled screw with fiducially rivet to facilitate track setting, one revolution corresponding to a
height difference of 1.25mm Lateral and horizontal adjustable are made separately at the two and one point
support respectively. V- slots are incorporated for positioning the four faced scaling rule. Vertical holes
accommodate a quick action shutter with an integral cable release for use in stroboscope photography. Large
catapult arms with slots for elastic bands are fitted to each end of the track. A pulley fitted to one end of the
track enables experiments involving acceleration under a constant force to be investigated. Identical end caps
enable air to be introduced from either end of the track, bung being supplied to close the end not being used.
The knurled screw, catapult arms and pulley mountings are matt black finish to aid the interpretation of
stroboscope photographs. Complete with supply of elastic bands.
Accessories Kit

Aluminium alloy vehicles have bee carefully designed to attain the optimum eight of buffer attachments.
Buffer attachments are located in holes 6.5mm diameter ad clamped by screw at each Ed of the vehicle. A
vertical 4mm diameter hole in the center of each vehicle enables the white plastics rod to be used to indicate
the positions of vehicles on stroboscope photographs. Vertical slots in the top of the vehicles enable white
cards to be positioned for photoelectric timing applications. The vehicles buffer attachment and clamping
screw are finished in matt black to the interpretation stroboscopic photographs
