Moment Of Inertia Of A Hinged Door

Moment of inertia is the measure of an object s resistance to changes in its rotation rate.

Moment of inertia of a hinged door.

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 door s moment of inertia for rotation on its hinges. Express your answer to two significant figures and include the appropriate units. Find the angular speed of the door just after the bullet embeds into it.

Solution for a uniform thin solid door has height 2 24 m width 0 873 m and mass 25 0 kg. 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. It is hinged at one end and rotates about a vertical axis practically without friction. What is the door s moment of inertia for rotation on its hinges.

When an object is just sitting without any motion the moment of inertia is 0. The moment of inertia depends on the mass of an object but it also depends on how that. A 23 kg solid door is 220 cm tall 95 cm wide. If you exert a force at the hinge the door will not move.

Find its moment of inertia for rotation on its hinges. 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. The moment of inertia of the door about the vertical axis at one end is ml 2 3. A 22 kg solid door is 220 cm tall 90 cm wide.

What is the moment of inertia of the door about the axis through its hinges. This maximizes the torque you exert. What is the door s moment of inertia for rotation about a vertical axis. 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.
