Applied Mechanics and Graphic Statics The following is not a law of static friction: The force of friction depends upon the roughness of the surface The force of friction is dependent upon the area of contact The force of friction always acts in a direction opposite to that in which the body tends to move The magnitude of the limiting friction bears a constant ratio to the normal reaction between two surfaces The force of friction depends upon the roughness of the surface The force of friction is dependent upon the area of contact The force of friction always acts in a direction opposite to that in which the body tends to move The magnitude of the limiting friction bears a constant ratio to the normal reaction between two surfaces ANSWER DOWNLOAD EXAMIANS APP
