With what force does a car weighing 1 tonne force push against the middle of a convex bridge

With what force does a car weighing 1 tonne force push against the middle of a convex bridge with a radius of curvature of 80m? Vehicle speed 54km / h

To calculate the desired pressure of a given car in the middle of the convex bridge, we apply the formula: F = P = m * (g – a) = m * (g – V ^ 2 / R).

Values of constants and variables: m – vehicle weight (m = 1 t = 1 * 10 ^ 3 kg); g – acceleration due to gravity (g ≈ 9.8 m / s2); V – vehicle speed (V = 54 km / h = 15 m / s); R is the radius of the bridge (R = 80 m).

Let’s make the calculation: F = m * (g – V ^ 2 / R) = 1 * 10 ^ 3 * (9.8 – 15 ^ 2/80) = 6.9875 * 10 ^ 3 H ≈ 7 kN.

Answer: The pressure force of a given vehicle is 7 kN.
