Suppose that the coefficient of friction between a typical tire and a particular highway surface is 0.75. What should be the minimum radius for curves on this highway if the speed limit is 55 miles per hour?

Measuring ? s. An easy way to measure the coefficient of static friction is to place two objects together and then tilt them until the top one slides. The angle at which one object starts to slip on the other is directly related to the coefficient. When the two objects are horizontal there is no frictional force. As the objects are slowly tilted, the force of static friction must increase...The coef?cient of static friction between the box and the surface is 0.40, and the coef?cient of kinetic friction is 0.20. (a) If no horizontal force is applied to the box and the box is at rest, how large is the friction force exerted on

## How To Find Minimum Coefficient Of Static Friction

### If the tires do not spin, determine the minimum coefficient of static friction between the tires and the road. Solution: The magnitude of the acceleration is a = (80mile/h)/8s = (35.76m/s)/8s = 4.47m/s 2 .

- Static frictional forces from the interlocking of the irregularities of two surfaces will increase to prevent any relative motion up until some limit where motion occurs. It is that threshold of motion which is characterized by the coefficient of static friction. The coefficient of static friction
