Answer:
The laws of limiting friction are:
(1) The direction of limiting friction force is always considered as opposite to the direction of motion.
(2) It always acts tangential to the two given surfaces.
(3) It is generally dependent on the material and also on the nature of the surfaceswith which it comes in contact.
Explanation:
As the constant applied force, Fa is always considered equal to limiting friction Fl and normal reaction R = mg.
So, the resultant of Fl and R is F, which makes an angle α with R. This angle is referred to as the angle of friction.
Hence, the coefficient of limiting friction is equal to the tangent of the angle of friction.
