Question

Which formula correctly calculates the maximum possible static friction, also known as the limiting force of friction (F_L​)?

Options

• \[F_L=\frac{\mu_s}{N}\]

• \[F_L=\mu_sN\]

• \[F_L=\mu_smg\]

• \[F_L=\frac{N}{\mu_s}\]

Answer 1

\[F_L=\mu_sN\]

Explanation:

This correctly shows that the limiting force of friction is directly proportional to the normal reaction, with the coefficient of static friction as the constant.
