In physics and mechanics, torque is the rotational analogue of linear force. [1] It is also referred to as the moment of force (also abbreviated to moment ). The symbol for torque is typically τ {\displaystyle {\boldsymbol {\tau }}} , the lowercase Greek letter tau .
Learn what torque is, how to calculate it, and how it differs from force and power. Explore the types, examples, and applications of torque in everyday life and physics.
Torque is either clockwise or counterclockwise relative to the chosen pivot point. Figure \(\PageIndex{1}\) shows counterclockwise rotations. Figure \(\PageIndex{1}\): Torque is the turning or twisting effectiveness of a force, illustrated here for door rotation on its hinges (as viewed from overhead). Torque has both magnitude and direction.
16 kwi 2024 · What is Torque? Torque in physics is only a force’s propensity to turn or twist. Torque is referred to using a variety of terms, including moment and moment of force. The moment arm or lever arm is the measurement of the separation between the point of application of force and the axis of rotation.
18 paź 2024 · Learn what torque is, how to calculate it, and how it affects rotational motion. Find out the types, formulas, units, and examples of torque in physics, and see how it is used in everyday situations.
Describe how the magnitude of a torque depends on the magnitude of the lever arm and the angle the force vector makes with the lever arm; Determine the sign (positive or negative) of a torque using the right-hand rule; Calculate individual torques about a common axis and sum them to find the net torque
What we have learned by describing torque in this section so far is that the location of the force is essential in order to determine torque. Thus, when drawing a force diagram on a selected system, we can no longer collapse the extended object(s) into a point, which we did when calculating forces.
