Question

What do you understand by angle of friction and angle of repose? Tell the relationship between them

✓

Answer

For any two planes, the static coefficient is equal to the tangent of friction.$
\Rightarrow \quad \lambda=\tan ^{-1}\left(\mu_{s}\right)
$
This is called angle of friction.
The maximum angle of inclination of the inclined plane with the horizontal direction at which the object remains in a state of perfect equilibrium on the inclined plane is called angle of repose.Angle of friction = Angle of repose.
Hence angle of friction and angle of repose both are equal.
