How to find minimum coefficient of static friction?
Understand the Problem
The question is asking how to determine the minimum coefficient of static friction, which typically involves understanding the forces acting on an object at rest, and how to calculate the coefficient using the formula that relates frictional force to normal force.
Answer
Divide the force trying to move the object by the normal force.
The minimum coefficient of static friction is calculated by dividing the force trying to move the object by the normal force.
Answer for screen readers
The minimum coefficient of static friction is calculated by dividing the force trying to move the object by the normal force.
More Information
The coefficient of static friction ( ext{μ}_s) is a dimensionless value that represents the ratio of the maximum static frictional force (before movement begins) to the normal force.
Tips
A common mistake is not correctly identifying the normal force, especially when inclined planes are involved. Be sure to account for all forces acting perpendicularly to the surface.
