Q7.31 A cylinder of mass and radius
is rolling perfectly on a plane of inclination
. The coefficient
of static friction .
(a) How much is the force of friction acting on the cylinder?
Consider the following figure :
Moment of inertia of the cylinder is :
Thus acceleration is given by :
or
Now using Newton's law of motion :
or
or
or
Hence frictional force is 16.3 N.
