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

A door can just be opened with 10N force on the handle of the door. The handle is at a distance of 50cm from the hinges. Then, the torque applied on the door (in Nm ) is

When a body is hinged at a point and a force is acting on the body in such a way that the line of action of force is at some distance from the hinged point, the body will start rotating about the hinged point. The angular acceleration of the body can be calculated by finding the torque of that force about the hinged point. A disc of mass m and radius R is hinged at point A at its bottom and is free to rotate in the vertical plane. A force of magnitude F is acting on the ring at top most point. Component of reaction at the hinge in the horizontal direction is

Why is the handle of a screw made wide ?

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 door 1.6 m wide requires a force of 1N to be applied at the free and to open or close it. The force that is required at a point 0.4 m distance from the hinges for o[ening or closing the door is

A nut cracker is used to crack a nut. In it nut is held in two arms at a distance 2 cm from the hinge and the handle of it is at a distance 25 cm from hinge. The force required to crack a walnut is 30 N. What is the minimum force required to crack it with the nut cracker. [2.4 N]
