Torqueforce

Torqueforce is a term used in engineering and physics to describe the effective linear force produced by a torque at a given radius from the axis of rotation. In its common usage, torqueforce refers to the tangential force that results when a torque is applied at a lever arm of length r, with the relation F_t = τ / r, where τ is the applied torque. The direction is tangential to the circular path of the lever arm.

In ideal, constant-radius systems, torqueforce is measured in newtons. When the radius varies during rotation, the instantaneous torqueforce changes with r and time, requiring dynamic calculation or averaging over a motion.

Applications include estimating contact forces in gears, clutches, brake discs, and robotic grippers, aiding torque budgeting and safety margins. It also informs performance testing and mechanical sizing in rotating machinery. Limitations: torqueforce is a simplification; real systems involve friction, wear, compliance, gear reductions, and dynamic effects that modify the relationship between torque and linear force.

The term's origin is informal; it appears in engineering discussions and some textbooks as a derived metric rather than a fundamental quantity. It is not universally standardized and may be used differently in various disciplines. See also torque, force, and rotational dynamics.
