Moment Of Inertia Of A Hinged Door

It is hinged at one end and rotates about a vertical axis practically without friction.

Moment of inertia of a hinged door.

Solution for a uniform thin solid door has height 2 24 m width 0 873 m and mass 25 0 kg. When an object is just sitting without any motion the moment of inertia is 0. A 22 kg solid door is 220 cm tall 90 cm wide. Find its moment of inertia for rotation on its hinges.

Homework equations i 1 12 m a 2 b 2 mr 2 parallel axis theorem the attempt at a solution i initially used the door height and width as a and b i m sure this is right and used the door thickness as the distance between axis. The moment of inertia of the door about the vertical axis at one end is ml 2 3. The easiest way to open a door is to exert a force on the side of the door opposite the hinge and to push or pull with a force perpendicular to the door. Express your answer to two significant figures and include the appropriate units.

The moment of inertia depends on the mass of an object but it also depends on how that. When you try to make it move that mean you want to change the speed of the object from 0 to any there will be moment of inertia effect. What is the door s moment of inertia for rotation on its hinges. Ignore the thickness of the door express your answer using two significant figures.

What is the door s moment of inertia for rotation on its hinges. What is the door s moment of inertia for rotation about a vertical axis. If you exert a force at the hinge the door will not move. A 23 kg solid door is 220 cm tall 95 cm wide.

Determine the moment of inertia of a 17 kg door that is 2 5 m high and 1 5m wide and is hinged along long side. Find the angular speed of the door just after the bullet embeds into it. The door is 1 0 m wide and weighs 12 kg. Moment of inertia is the measure of an object s resistance to changes in its rotation rate.
