Static Friction is considered one of the most asked concept.
-
6 Questions around this concept.
Solve by difficulty
A block rests on a rough inclined plane making an angle of 30o with the horizontal. The coefficient of static friction between the block and the plane is 0.8. If the frictional force on the block is 10 N, the mass of the block (in kg) is
(take g = 10 m/s2 )
Concepts Covered - 1
Static Friction
-
It occurs when there is a tendency of relative motion, i.e, the body is still at rest and is just about to move.
-
When two bodies do not slip over each other, then the force of friction is called static friction.
-
It is a variable force or self-adjusting force as it changes itself according to the applied force.
-
It is denoted by fs and the static friction is in between:-
where fl is limiting friction.
5. Limiting friction is the maximum static friction that a body can exert on the other body in contact with
It and is given by:-
or
