kthouz said:I know that in the simple pendulum there is a rextoring force created by the gravity. My question now is, when we take the case of the physical (real) pendulum there is an other stuff which come in "the restorung torque" how is this created. What is infact its axis of rotion?
Restoring torque is the force that acts on a physical pendulum, causing it to return to its equilibrium position after being displaced. It is created by the weight of the pendulum's mass and the force of gravity.
The length of a physical pendulum directly affects the restoring torque. A longer pendulum will have a greater restoring torque than a shorter pendulum because the weight of the mass will act over a longer distance, creating a larger force.
Apart from the length of the pendulum, the restoring torque can also be affected by the mass of the pendulum, the angle of displacement, and the strength of gravity. These factors determine the size and direction of the restoring torque.
The restoring torque plays a crucial role in the motion of a physical pendulum. It causes the pendulum to oscillate, or swing back and forth, with a constant period and amplitude. Without the restoring torque, the pendulum would not be able to return to its equilibrium position.
Yes, the restoring torque of a physical pendulum can be increased by increasing the length of the pendulum, adding more weight to the mass, or increasing the angle of displacement. However, there is a limit to how much the restoring torque can be increased, as it is also dependent on the strength of gravity.
