The drawing illustrates an overhead view of a door and its axis of rotation. The axis is perpendicular to the screen. There are four forces acting on the door, and they have the same magnitude. Rank the torque τ that each force produces, largest to smallest.

To rank the torque τ produced by each force, largest to smallest, we need to consider the distance between the axis of rotation and the line of action of each force.
Here are the steps to rank the torque:
1. Identify the four forces acting on the door.
2. Determine the magnitude of each force. Let's say the magnitude of each force is F.
3. Analyze the distance between the axis of rotation and the line of action for each force.
4. The torque τ produced by a force is given by the formula τ = F * d, where d is the perpendicular distance between the axis of rotation and the line of action of the force.
5. Compare the distances for each force and rank the torques accordingly. The force with the largest distance will produce the largest torque, and the force with the smallest distance will produce the smallest torque.
Remember, the torque is directly proportional to the distance between the axis of rotation and the line of action of the force. So, the greater the distance, the larger the torque produced by the force.
To rank the torque (τ) produced by each force acting on the door, we need to understand the concept of torque. Torque is the rotational equivalent of force and is defined as the product of the force applied and the perpendicular distance from the point of rotation (or axis) to the line of action of the force.
In this case, since the axis of rotation is perpendicular to the screen, the perpendicular distance for each force will be the shortest distance from the axis to the line of action of the force.
To determine the torque produced by each force, we can follow these steps:
1. Study the drawing carefully to identify the four forces acting on the door. Note their directions and positions in relation to the axis of rotation.
2. Determine the perpendicular distance for each force. This can be done by drawing a line perpendicular to the axis of rotation from the axis to the line of action of each force. Measure the length of these lines to determine the perpendicular distance.
3. Calculate the torque for each force by multiplying the magnitude of the force by the perpendicular distance. Note that the magnitude of the forces is given as equal in the question.
4. Rank the torques in descending order, from largest to smallest.
Remember that torque depends on both force and distance, so even if the forces have the same magnitude, their effect on the torque can differ due to the perpendicular distance from the axis of rotation.
By following these steps, you will be able to rank the torques produced by each force, largest to smallest.
