Description
This apparatus allows single-direction motion to
be studied whilst virtually eliminating friction
thanks to the air cushion technique.
This consists of creating a thin cushion of air
between 2 flat parts (track and glider) and
raising the glider slightly, thereby eliminating
friction. To achieve this, compressed air is
injected into the cavity underneath the track,
which has small holes all along its length (cf.
diagram opposite).
Setting up and use
1-
Basic setup
-
Take the track out of the cardboard
tube.
Fix
the
adjustable
feet
underneath the track at either end
(foot alone on one side and adjusting
bar on the other).
-
Place the spirit level on the glider and place
the glider on the track. Then adjust until the
glider is perfectly horizontal by turning the
adjusting screws.
-
Connect the hose to the track inlet.
Unscrew the plug, slide it onto the hose
with the white flange.
Screw the plug onto the fitting.
