Question

Now calculate the normal force exerted by the road on the car at point B.

And finally calculate the normal force exerted by the road on the car at point C.

A car with a mass of 1190 kg is traveling in a mountainous area with a constant speed of 64.5 km/h. The road is horizontal and flat at point A, horizontal and curved at points B and C. The radii of curvatures at B and C are: rB = 135 m and rC = 120 m. Calculate the normal force exerted by the road on the car at point A. Now calculate the normal force exerted by the road on the car at point B. And finally calculate the normal force exerted by the road on the car at point C.

Explanation / Answer

The radii of curvatures at B and C are: rB= 135 m and rC= 120 m. Calculate the normal force exerted by the road on the car at point A m = 1130; g = 9.81

v = 69.4*5/18 [m/s]

rb = 160; rc = 120

Now calculate the normal force exerted by the road on the car at point B.

b) m*g = N + (m*v*v/rb)

N = 8461 N

And finally calculate the normal force exerted by the road on the car at point C.

c) m*g + (m*v*v/rc) = N

N = 14585 N
