Moment Of Inertia Of A Hinged Door

When an object is just sitting without any motion the moment of inertia is 0.

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. 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. 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.

What is the door s moment of inertia for rotation on its hinges. The door is 1 0 m wide and weighs 12 kg. What is the door s moment of inertia for rotation about a vertical axis inside the door 12 cm from one edge. This maximizes the torque you exert.

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

It is hinged at one end and rotates about a vertical axis practically without friction. A 23 kg solid door is 220 cm tall 95 cm wide. The moment of inertia depends on the mass of an object but it also depends on how that. 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. What is the moment of inertia of the door about the axis through its hinges. Solution for a uniform thin solid door has height 2 24 m width 0 873 m and mass 25 0 kg. A 22 kg solid door is 220 cm tall 90 cm wide.
