1. Safety instructions
To avoid injuries:
• Maintain a safe distance from the device
while it is in operation. Be especially careful
to keep your eyes and face away from mov-
ing parts.
• Do not use your hand to spin the apparatus
to a high angular velocity! The screws are
not designed to stay in position at high ve-
locities and the weights will fly off.
2. Description
The rotary motion apparatus is used for investi-
gating the effect of a constant torque on a rotat-
ing body with variable moment of inertia.
A vertical, rotating axle on ball bearings in a
stable frame.supports a crossbar with equidis-
tant grooves for holding the weights. For safety,
the weights are fixed in place with screws. The
torque is generated by a rotating plate with
hooks and up to three slotted weights, acting via
a string threaded over a multiple pulley with four
different pulley diameters.
