It is known that a roller working on asphalt paving, having a support area of 1500 cm2

It is known that a roller working on asphalt paving, having a support area of 1500 cm2, produces a pressure of 300 kPa. What is the weight of the cat?

To find out the weight of the asphalt roller under consideration, we will use the formula: F = Pк = P * S, where P is the pressure produced by the roller (P = 300 kPa = 300 * 10 ^ 3 Pa); S is the support area of the considered roller (S = 1500 cm2, in the SI system S = 0.15 m2).

Let’s perform the calculation: Pk = P * S = 300 * 10 ^ 3 * 0.15 = 45 * 10 ^ 3 N.

Answer: The weight of the asphalt roller in question should be 45 kN.
