FMD8004 Rotation Theorem Demonstrator

Product DetailsDETAILS

• Product Introduction

  Experimental Demonstration Instrument for Rotation Theorem（Rotating Theorem Demonstrator）It is to use pulleys to reduce the influence of friction between the suspension line and the workbench on experimental phenomena.

  Purpose of the experiment:

  Observe the relationship between angular acceleration, torque, and moment of inertia.

  Experimental principle:

  When the torque is the same, the moment of inertia is the same, and the angular acceleration and rotational speed are also the same.

  When the torque is the same, the smaller the moment of inertia, the greater the angular velocity.

  Technical Indicators:

  The pulley support frame has a diagonal angle of 33 degrees and is equipped with a highly stable anti rust metal paint base;

  High strength chrome plated bracket, pulley and steel ball;

  A set of weights;

  Specification size: 720 × 400 × 360mm;

  Experimental operation:

  1. Fix the heavy objects on both sets of devices at the same position from the axis.

  2. Wrap equal length ropes around the pulleys of the two devices, and hang weights of equal mass on the ropes. Wrap both weights to the highest position and simultaneously apply two rotating systems to start rotating under the torque of the weights. It can be seen that under the same torque, the two systems have the same moment of inertia, angular acceleration, and rotational speed.

  3. Fix the heavy objects on one set of devices far away from the axis, while fixing the heavy objects on another set of devices very close to the axis.

  4. Wrap the weight to a high position and simultaneously apply two rotating systems to start rotating under the torque of the weight. It can be seen that the system with heavy objects close to the axis rotates faster, while the other one rotates slower. When the torque is the same, the smaller the moment of inertia, the greater the angular velocity.
