Vehicle weight 2t. What will be the pressure force of the car at the lowest point

Vehicle weight 2t. What will be the pressure force of the car at the lowest point of the concave bridge, the radius of curvature of which is 100 m? … Vehicle speed is 36 km / h.

Initial data: m (vehicle weight) = 2 t; the car is moving along a concave bridge; R (radius of curvature of the bridge) = 100 m; V (constant vehicle speed) = 36 km / h.

Constants: g (acceleration due to gravity) = 10 m / s2.

SI: m = 2 t = 2 * 10 ^ 3 kg; V = 36 km / h = 10 m / s.

The force of pressure (weight of the car) at the bottom point of the trajectory when moving in a circle can be calculated by the formula: P = m * an + m * g = m * (V ^ 2 / R + g).

Calculation: P = 2 * 10 ^ 3 * (10 ^ 2/100 + 10) = 2 * 10 ^ 3 * 11 = 22 * 10 ^ 3 H = 22 kN.
