![]() The r variable represents the moment arm’s length, while Theta is that the angle found between the momentum arm and the force vector. T represents the torque vector produced by a specific force, which is represented by F. Let’s take another look at the equation for torque: Now that we’ve defined torque, understanding the equation for torque calculation is a little easier. ![]() Photo: By Krishnavedala – Own work, CC0, The “moment arm” is the radius at which the supplied force acts upon, from the point of rotation to the point that the force is applied. Engineers may occasionally use the term “momentum of force”, or simply “momentum” as a substitution for torque. When you accelerate, this is an example of dynamic torque since angular acceleration is produced, and the wheels of your car move it from one position to another.įor the purposes of clarification, let’s note here that “torque” is not the only way to describe force producing angular acceleration. Meanwhile, an example of dynamic torque is starting your car and driving it. While the force would be being applied to the door, there is no rotation of the doors hinges, and thus the torque is static. If the door you were trying to open it was closed and you were pushing on it, this would be static torque. Static torque is torque that does not result in acceleration across an axis, a force which fails to produce angular acceleration. When measuring torque, it can be either dynamic or static in nature. The force that is used to generate the motion of opening the door is the torque. So while the door would still move the same amount, one act would require much less force than the other act. If you want to try and open a door by pushing on the side of the door closest to the hinge, you would need much more force to do it. When you go to open a door, you put your hand on the knob and push/pull it open, so this means you are exerting force on the door at a point in space furthest from the hinge. One of the easiest ways to illustrate an example of torque is by examining the motion of a door as you open it.
