Final answer:
Torque refers to the rotational force that causes an object to rotate, often described as the rotational equivalent of linear force. It is determined by the magnitude of the applied force, its direction, and its point of application.
Step-by-step explanation:
Torque is generally referred to as the rotational force generated by a motor or the force that causes an object to rotate about an axis. The magnitude, direction, and point of application of the force are all critical in defining torque.
The magnitude of torque (t) can be calculated using the equation t = rF sin θ, where r represents the distance from the pivot point to the point where the force is applied, F is the force applied, and θ is the angle between the force vector and the direction of the arm.
To put it simply, torque is the rotational equivalent of linear force. It tells us how effectively a force can produce or change the rotation of an object.
An example of torque in action is when you use a wrench to turn a nut. The force applied at a greater distance from the pivot (the nut) results in a larger torque, making it easier to turn the nut.
