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 moving parts.
•
Do not use your hand to spin the apparatus to
a high angular velocity! The plastic fasteners
are not designed to stay in position at high ve-
locities and the weights will fly off.
7 Slotted weight, red, 20 g
8 Hollow aluminium rod
9 Plastic weight fasteners
10 Spindle
11 Base and mount
The rotational motion apparatus is used for deter-
mining the angular acceleration as a function of
torque and for determining the moment of inertia
as a function of the distance of the body from the
axis and its mass.
A vertical, rotating axle with agate bearing supports
a crossbar for holding the weights. The force of the
driving weight is transferred via a pulley and a cord
wrapped around a spindle on the axis.
