s = 4 square meters – surface area on which a certain force acts;
P = 2 Newton / square centimeter – the pressure produced by the force.
It is required to determine F (Newton) – the value of the force.
Let’s convert the units of measurement of area from square meters to square centimeters:
s = 4 m2 = 4 * 10 ^ 4 = 40,000 cm2.
Then, to determine the strength, you must use the following formula:
P = F / s, from here we find that:
F = P * s = 2 * 40,000 = 80,000 Newtons (80 kN).
Answer: a force equal to 80 kN acts on the surface.
