With what force does the body act on a support with a cross-sectional area of 20 cm2, if this creates a pressure of 800 kPa?

To calculate the force acting on the used support, we will use the formula: F = P * S.

Variables: P – pressure created by the body on the support (P = 800 kPa = 800 * 10 ^ 3 Pa); S is the cross-sectional area of the support (S = 20 cm2 = 20 * 10 ^ -4 m2).

Let’s make a calculation: F = P * S = 800 * 10 ^ 3 * 20 * 10 ^ -4 = 1600 N or 1.6 kN.

Answer: The body acts on the used support with a force of 1.6 kN.
