Part of riding a bicycle involves leaning at the correct angle when making a turn. To be in equilibrium the total force exerted by the ground must be on a line through the center of gravity (CG) of the bicycle and rider, as indicated on the figure below. Turns on ice are much more difficult to negotiate than turns on concrete. What is the minimum coefficient of static friction required for a person with mass of 75 kg to negotiate the curve at a velocity of 8.0 m/s and with a turn radius of 25.0 m?

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.
