On the support of what area should a load m = 20 be placed in order to produce a pressure of 400 Pa?

To find out the required area of the used support, consider the formula: Sх = Ft / P = mg * g / P, where mg is the mass of the delivered load (mg = 20 kg); ); g – acceleration due to gravity (const, g ≈ 10 m / s2); P is the required pressure on the support used (P = 400 Pa).

Let’s perform the calculation: Sх = mg * g / P = 20 * 10/400 = 0.5 m2.

Answer: The area of the support used should be 0.5 m2.
