Angle of Friction and Repose

Minimum force is needed to move a block on rought surface, if theta = angle of friction. Angle of friction and angle of repose are numerically same.

Consider the following statements A) Angle of repose is equal to angle of friction B) Angle of friction is independent of coefficient of friction

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 .

Define angle of friction, angle of repose and obtain the relation for angle of repose (ie., theta _(g) = tan ^(-1) mu).

Consider the following A and B, and identify the correct choice in the given answers. A) For a body resting on a rough horizontal table, it is easier to pull at angle that push at the same angle to cause motion B) A body sliding down a rough inclined plane of inclination equal to angle of friction has nonzero acceleration

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.

Calculate angle of friction between wedge and block system is at rest M coefficient of friction between wedge and block.

A body of weight 20N is on a horizontal surface, minimum force applied to pull it when applied force makes an angle 60° with horizontal (angle of friction a = 30°) is
