Hi ,
The Static Friction force of an object on a ramp(inclined plane) making an angle with the horizontal is greater than the weight component down the ramp. My textbook says that this means that the object on the ramp is stationary as the frictional force is greater than the weight component force down the ramp. However for an object to be still or in equilibrium shouldn't the forces add up to 0. In this case if the frictional force is greater, the object should technically be moving up the ramp and intuitively this is obviously wrong so could someone please clarify this for me ? as I am a bit confused..
