प्रश्न
State the effect of force F in of the following diagram.
उत्तर १
Wheel turns about the axis of rotation i.e. about pivot on applying force.
उत्तर २
In the given diagram, the force F is applied tangentially to the wheel at its edge. The effect of this force is:
-
Rotational Motion: The force F causes the wheel to rotate about its pivot. This is due to the creation of a torque, which depends on the magnitude of the force and the distance from the pivot.
-
Translational Motion (if friction permits): The wheel may also move forward (translate) if there is sufficient friction between the wheel and the surface.
Thus, the force causes rotation and possibly translation of the wheel.
