Adjustable Feet Attach the feet to the track as illustrated.
Turn the feet screws to level the track then tighten the lock nuts
to secure them.
For maximum stability, position the feet about 1/4 of the track
length from each end
Adjustable End Stops Attach the end stops to the track
as illustrated. The end stops contain magnets to repel the mag-
netic bumper of a cart. A stud is provided as an attachment
point for a spring.
Harmonic Springs Ideal for studying harmonic oscillation
of carts on a flat or inclined track, these spring hook onto holes
at the ends of the carts and to studs on top of the end stops. The
springs are packed in storage tubes, which include adhesive
tape so that they may be permanently attached to the underside
of the track.
Friction Block The friction block has two different surfaces (wood and felt) and
two different surface areas for studying friction. It includes an eye screw for attaching
a string and slots on both broad surfaces for holding a picket fence (such as PASCO
part ME-9804) or the included angle indicator.
