A car of mass 3 tons moves uniformly on a convex bridge with a radius of curvature v = 50 m, having a speed v = 36 km/h. At what point on the bridge will the vehicle pressure be greatest? Find this pressure. (The position of the bridge points is determined by the angle between the direction of the straight line from the center of curvature to the point under study and the vertical.) What is the effect of the speed of the car on the force of its pressure on the bridge?
