There is a 25cm thick concrete slab on the floor. Determine the pressure of the slab on the floor.

Data: h (concrete slab thickness) = 25 cm (0.25 m).

Reference values: ρb (concrete density, for heavy concrete ρb = 2200 .. 2500 kg / m3) = 2350 kg / m3; g (acceleration due to gravity) = 9.81 m / s2 ≈ 10 m / s2.

The pressure of a concrete slab can be calculated using the formula: P = F / S = m * g / S = ρb * V * g / S = ρb * h * S * g / S = ρb * h * g.

Let’s make the calculation: P = 2350 * 0.25 * 10 = 5875 Pa.

Answer: A concrete slab exerts a pressure of 5875 Pa on the floor.
