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 mm
• Radii of multiple pulley: 4,5 mm / 9,0 mm
• Driving weights: 10 g / 20 g / 30 g / 40 g / 50g
• Inertial mass of disc(s): 100 g / 200 g / 300 g
• Dimensions of base plate: 200 × 140 mm
• Total weight: 1,3 kg approx.

Contents:

• 1 Basic apparatus
• 2 100-g discs
• 2 200-g discs
• 1 Holder for slotted weights 10 g
• 2 Slotted weights10 g
• 1 Slotted weight 20 g
• 1 Pulley
• 1 Roll of string

Additionally required:

• 5401.U40160230 Digital Stroboscope (115 V, 50 / 60 Hz)
