Determinant of the force acting on a surface with an area of 4m2, if the pressure produced by it is 2 N / cm2


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.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
