A roller working on asphalt paving will produce a pressure of 300 kPa, and determine the weight of the roller if its support area is 1500 cm2.
Data: P is the pressure produced by the roller used (P = 300 kPa = 3 * 10 ^ 5 Pa); S is the total area of the roller support (S = 1500 cm2; in the SI system S = 0.15 m2).
To determine the desired weight of the roller used, consider the formula: Pcat = P * S.
Calculation: Pcat = P * S = 3 * 10 ^ 5 * 0.15 = 0.45 * 10 ^ 5 N.
Answer: The roller used has a weight of 45 kN.
