How does this increase the torque? Group of answer choicesIt increases the lever arm.It increases the force you can apply.It changes the angle you can apply the force relative to the lever arm.
Solution
Torque is a measure of the force that can cause an object to rotate about an axis. It is calculated by multiplying the force applied by the distance from the axis of rotation to the point where the force is applied (this distance is known as the lever arm).
-
Increasing the lever arm: If you increase the distance from the axis of rotation (the lever arm), you increase the torque. This is because torque is directly proportional to the lever arm length. For example, using a longer wrench to turn a bolt makes the task easier because it increases the lever arm and thus the torque.
-
Increasing the force: Similarly, if you increase the force applied, you also increase the torque because torque is directly proportional to the force applied. For example, pushing harder on a door (increasing force) makes it open faster (increases torque).
-
Changing the angle: The angle at which the force is applied also affects the torque. If the force is applied perpendicular to the lever arm, it maximizes the torque. If the force is applied at an angle, only the component of the force that acts perpendicular to the lever arm produces torque. So, changing the angle can either increase or decrease the torque, depending on the direction of change.
