The maximum static friction force on a body is f = μN. Static friction is best described as
Aself-adjusting up to a maximum
Bzero when the body is at rest
Calways equal to μN
Dindependent of applied force
Answer & Solution
Correct answer: A. self-adjusting up to a maximum
Static friction adjusts to match the applied force up to a maximum of μ_s·N; only at the verge of slipping does it equal μ_s·N.
