Torque is a measure of the force that can cause an object to rotate about an axis. It is the rotational equivalent of linear force. Torque is the tendency of a force to turn or twist an object. It is generally measured in pounds per foot or newtons per meter. Torque is a vector quantity, and its direction depends on the direction of the force on the axis. Torque can be calculated by multiplying the force applied by the distance from the axis of rotation. The formula for torque is τ = r x F, where τ is torque, r is the distance from the axis of rotation, and F is the force applied. Torque is used in many real-life applications, such as in automobiles, where it is the expression of a rotational or twisting force. Some examples of objects that experience torque include seesaws, wrenches, and gyroscopes.
