Determine the pressure exerted on the soil by a roller weighing 45 kN, if its support area is 0.15 m2.

These tasks: Pk (weight of the considered roller) = 45 kN (45 * 10 ^ 3 N); S (roller support area) = 0.15 m2.

To determine the pressure that the considered roller exerts on the soil, we use the formula: P = F / S = Pk / S.

Calculation: P = F / S = 45 * 10 ^ 3 / 0.15 = 300 * 103 Pa (300 kPa).

Answer: The roller in question exerts a pressure of 300 kPa on the soil.
