Answer 2

Calculating the Weight of the Roller

To calculate the weight of the roller, we can use the formula:

Weight (m) = Pressure (P) * Area (S) / Acceleration due to gravity (g)

Given: - Pressure (P) = 400 kPa - Area (S) = 0.12 square meters - Acceleration due to gravity (g) = 9.8 m/s^2

Using the formula, we can calculate the weight of the roller:

Weight (m) = P * S / g

Weight (m) = 400,000 * 0.12 / 9.8

Weight (m) ≈ 4,897 kg

Therefore, the weight of the roller is approximately 4,897 kg.
