four examples related to " moment of force"
Answers
Answer:
There are many examples of moment of force which we see in common life
here are some of them:-
1. To open and shut the door we apply Air Force which is normal to the door at its handle which is provided at the maximum distance you can noticed that the force which we apply is much greater than the force which is required to open the door at the Hinges rather than on the handle itself hence the moment of force is executed here. since the handle is provided at the maximum distance from the door there we require much less force to open the door.
2. The upper circulars stone of a hard floor grinder is provided with a handle near its him that is at the maximum distance from the center so that it can easily be rotated about the iron pivot at its center by applying a small force at the handle.
3. For turning of steering wheel a force is applied tangentially on the rim of the wheel. the sense of rotation of wheel is changed by changing the point of application of force without changing the direction of force.
4. Send a particular amount of force is applied at any point of the wheel that is most appropriately at the rim of the wheel real rotates anticlockwise. the rotation of the wheel is clockwise when the force is applied in the same direction at the point where which it is applied in the desirable direction.
