hello good morning. Let look at the two diagram. (back view) In STATIC, a car is remauning static at a bank curve and its force diagram is as follows. for this case, the normal force is smaller than the weight of the car and friction exists in the directiin perpendicular to car. In MOTION, the car is moving into the screen and is surrounding a banked curve. now what i am so surprised with is that THE MECHANISM OF FORCE CHANGING. if we inspect a car changes it state from.diagram 1 to 2, we wil actually realize that the normal force gradually increases until its vertical component Ncos(∠) is equal to the mg and balances the weight of the car. meanwhile there is an unbalanced component that causes centripetal force ,Nsin(∠) . Can anyone explain to me the actual mechanism of this changes in normal force?? or correct me if i am wrong.
