Moment Of Inertia Of A Hinged Door

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.

Moment of inertia of a hinged door.

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. Ignore the thickness of the door express your answer using two significant figures. 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. It is hinged at one end and rotates about a vertical axis practically without friction.

If you exert a force at the hinge the door will not move. What is the door s moment of inertia for rotation on its hinges. Find the angular speed of the door just after the bullet embeds into it. What is the door s moment of inertia for rotation about a vertical axis.

The moment of inertia of the door about the vertical axis at one end is ml 2 3. What is the door s moment of inertia for rotation about a vertical axis inside the door 12 cm from one edge. What is the moment of inertia of the door about the axis through its hinges. The moment of inertia depends on the mass of an object but it also depends on how that.

The door is 1 0 m wide and weighs 12 kg. Find its moment of inertia for rotation on its hinges. A 22 kg solid door is 220 cm tall 90 cm wide. 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.

This maximizes the torque you exert. Solution for a uniform thin solid door has height 2 24 m width 0 873 m and mass 25 0 kg. Express your answer to two significant figures and include the appropriate units. What is the door s moment of inertia for rotation on its hinges.
