The handle of a door is at a distance `40cm` from axis of rotation. If a force `5N` is applied on the handle in a direction `30^@` with plane of door, then the torque is

The handle of a door is at a distance 40 cm from axis of rotation. If a force 5Nis applied on the handle in a direction 30^(@) with plane of door, then the torque is

The hinge of door is at a distance of 40 cm from the point of application of force. If a force of 20 N is applied, what is the magnitude of moment of force ?

Why the handles of the doors are at maximum distance from the hinges?

To push open a door, a person applies a force of 75 N on the handle of the door, at an angle of 60^(@) from the normal to its plane. If the handle is located at a distance of 80 cm from its hinge, find the torque applied by him.

A particle is at a distance r from the axis of rotation. A given torque tau produces some angular acceleration in it. If the mass of the particle is doubled and its distance from the axis is halved, the value of torque to produce the same angular acceleration is -

A particle is at a distance r from the axis of rotation. A given torque tau produces some angular acceleration in it. If the mass of the particle is doubled and its distance from the axis is halved, the value of torque to produce the same angular acceleration is -

A force of 36N is applied to a particle located at 0.15 m from the axis of rotation. What is the magnitude of the torque about this axis, if the angle between the direction of the applied force and radius vector is (a) 120^(@) (b) 45^(@) ?
