Task data: S (area of the taken support) = 400 cm2 (in SI system S = 400 * 10 ^ -4 m2); m (body weight acting on the support) = 12 kg.
Constants: g (acceleration due to gravity) ≈ 10 m / s2.
1) Determine the force of pressure of the body on the taken support: F = m * g = 12 * 10 = 120 N.
2) Determine the pressure on the taken support: P = F / S = 120 / (400 * 10 ^ -4) = 3 * 10 ^ 3 Pa (3 kPa).
Answer: The force of pressure on the taken support is 120 N; the pressure is 3 kPa.
