When a vehicle moves along a horizontal curved road on a mountain, the necessary centripetal force is supplied by the force of friction between the wheels of the vehicle and the surface of the road. Thus, to provide necessary centripetal force, mountains have an inward inclination at sharp turns.
How do they make tunnels through mountains?
require little or no extra support during construction and are often used as railways or roadways through mountains. Years ago, engineers were forced to blast through mountains with dynamite. Today they rely on enormous rock-chewing contraptions called tunnel boring machines.
