Rotation Apparatus

Rotating apparatus for determining angular acceleration as a function of the torque and for determining the moment of inertia depending on mass and distance from an axis.An axle on agate bearings supports a cross bar to which weights can be attached. The force from a driving weight is conveyed to the axle via a string wrapped around the axle and passed over a pulley and a second multiple pulley on the axle itself.Length of crossbar: 600 mmRadii of multiple pulley: 4.5 mm / 9.0 mmDriving weights: 10 g / 20 g / 30 g / 40 g / 50gInertial mass of disc(s): 100 g / 200 g / 300 gDimensions of base plate: 200 x 140 mm 2Total weight: 1.3 kg approx.Contents:1 Basic apparatus2 100-g discs2 200-g discs1 Holder for slotted weights 10 g2 Slotted weights10 g1 Slotted weight 20 g1 Pulley1 Roll of string
