Determine the force acting on a surface of 4 square meters if the pressure produced by it is 20 kN.
| July 10, 2021 | education
Initial data: S (surface area under pressure) = 4 m ^ 2; P (pressure on a given surface) = 20 kPa = 20 * 10 ^ 3 Pa.
The force that acts on a given surface is determined from the formula: P = F / S, whence F = P * S.
Let’s perform the calculation: F = 20 * 10 ^ 3 * 4 = 80 * 10 ^ 3 H = 80 kN.
Answer: A force of 80 kN acts on a given surface.
