Torque is a measure of the turning or twisting force on an object. In the context of a door, torque is important because it determines how easily the door can be opened or closed.
To calculate torque, you need to know the magnitude of the force and the distance from the pivot point or axis of rotation. The formula for torque is T = F x d, where T is torque, F is force, and d is distance.
The 6 forces that can act on a door are: weight, friction, tension, compression, shear, and bending. These forces can come from various sources, such as gravity, wind, or human interaction.
The ranking of the torque magnitudes will depend on the specific situation and the magnitude of each force. Generally, the weight of the door and any additional weight on the door (such as from objects hanging on it) will have the greatest torque magnitude, followed by friction, tension, compression, shear, and bending.
To reduce the torque on a door, you can decrease the magnitude of the forces acting on it, such as by removing objects hanging on the door. You can also decrease the distance from the pivot point to the force, which will decrease the torque according to the formula T = F x d. Additionally, you can add support or reinforcement to the door to distribute the forces more evenly and reduce the overall torque.
