ANGLE OF FRICTION

If force F is gradually increased from zero to 50 N , tehn (a) find the minimum contact force, (b) find the maximum value of angle of friction when F = 30 N , (d) find the angle of friction when the block is moving with constant velocity and ( e) sketch a graph between friction and applied force.

Assertion: A body slides down an inclined plane if the angle of friction is more than the angle of the inclined plane with the horizontal. Reason : When the angle of inclination is equal to the angle of friction, the component of weight parallel to the plane is just sufficient to overcome the frictional force.

The angle between the resultant contact force and the normal force exerted by a body on the other is called the angle of friction. Show that it lamda be the angle of friction and mu the coefficient of static friction. lamdaletan^-1mu .
