1.	Define angle of friction. Deduce its relation with co-effecient of friction.
Answer» Ans :- angle of friction the angleof a plane to the horizontal when a body placed on the plane will just start to slide. The tangent of theangle of frictionis the coefficient of static friction. The coefficient of friction between any two surfaces in contact is defined as the ratio of the force of limiting friction and normal reaction between them. u= F / R Angle with the resultant of force of limiting friction F and normal reaction R makes with the direction of normal reaction R is angle of reaction.

Ans :- angle of friction the angleof a plane to the horizontal when a body placed on the plane will just start to slide. The tangent of theangle of frictionis the coefficient of static friction.

The coefficient of friction between any two surfaces in contact is defined as the ratio of the force of limiting friction and normal reaction between them.

u= F / R

Angle with the resultant of force of limiting friction F and normal reaction R makes with the direction of normal reaction R is angle of reaction.
