As shown in figure, the hinges `A` and `B` hold a uniform `400N` door in place. The upper hinge supports the entire weight of the door. Find the resultant force exerted on the door at the hinges, the width of the door is `h/2`, where `h` is the distance between the hinges.

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

The figure shows the top view of a door that is 2 m wide. Two forces are applied to the door as indicated. What is the magnitude of the net torque on the door with respect to the hinge?

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

We cannot open or close the door by applying force at the hinges. Why?

A vertical rectangular door with its centre of gravity at O (see figure) is fixed on two hinges A and B along one vertical length side of the door. The entire weight of the door is supported by the hinge A . Then the free body force diagram for the door (the arrows indicate the direction of the forces) is

Consider the door of a room of wieght W hinged at two points as shown in the diagram. If the magnitude of forces by the hings on the door are equal, find the magnitude of force.
