Question:easy

The co-efficient of friction ($a$) in terms of angle of friction ($f$) is given by:

Show Hint

The tangent of the angle of friction is always equal to the coefficient of static friction:
\[ \mu = \tan\phi \implies \phi = \tan^{-1}(\mu) \]
This relationship is used to measure the coefficient of friction experimentally on an inclined plane.

$\phi = \tan\mu$
$\mu = \sin\phi$
$\mu = \tan\phi$
$u = \frac{1}{\tan\phi}$
