Torque

[fayt]

The net force acting on a body accelerates it. But it takes something to give the body an angular acceleration. A force is needed, but it must be applied in a way that creates a twisting or turning action. Torque, τ is the rotational version of force, and results from the application of one or more forces. Torque is specified relative to a chosen rotation axis or pivot.

Torque is dependent upon

-The distance from the rotation axis to the force application point (Refer to first figure).
-The magnitude of the force, F.
-The orientation of the force relative to the displacement from the axis to force application point (refer to second figure).



Definition: The torque produced by a force is defined by:

τ = R x F → τ = R x F sinθ

The SI units of torque are Newton-metre (N.m).

F┴ is the perpendicular component of the force (also known as the tangential component) and is called the lever arm or moment arm of the force. It is the perpendicular distance from the rotation axis to the line of action of the force.

ay akala ko cell phone na torque or kaya power tools na torque ... hehehehe

Pwede adobong tuyo o kaya adobo sa gata.  Dapat bata pa ung torque para hindi matigas.
