Concept explainers

Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

6. Part of riding a bicycle involves leaning at the correct angle when making a Free-body diagram turn, as seen in the Figure. To be stable, the force exerted by the ground must be on a line going through the center of gravity. The force on the bicycle wheel can be resolved into two perpendicular components- N w friction parallel to the road (this must supply the centripetal force), and the vertical normal force (which must equal the system's weight). F = sum of w N and f (a) Show that 0 (as defined in the figure) is related to the speed V and radius N = w f of curvature r of the turn in the same way as for an ideally banked roadway- that is, o = tan¬' v² / rg (b) Calculate 0 for a 12.0 m/s turn of radius 30.0 m (as in a race).
