Question

Angle of repose of a rough inclined plane is 60 degree what is the coefficient of friction

Answer 1

from the figure,

if theta = 60 ,

tan theta = tan60 = Ul = √3

Answer 2

Given that,

Angle of repose of a rough inclined plane is 60 degree.

To find,

The coefficient of friction.

Solution,

In this case,

$mg\sin \theta=\mu mg\cos\theta\\\\\mu=tan\theta\\\\\mu=tan(60)\\\\\mu=1.73$

So, the coefficient of friction is 1.73.
