A reinforced concrete slab measuring 4 x 0.3 m and 25 cm thick is submerged in water by a third of its volume. Determine the buoyancy force acting on it.
l = 4 m.
b = 0.3 m.
d = 25 cm = 0.25 m.
ρ = 1000 kg / m ^ 3.
g = 9.8 m / s ^ 2.
Farkh -?
Farch = ρ * g * V1.
V1 = V / 3
V = l * b * d.
V1 = l * b * d / 3.
Farch = ρ * g * l * b * d / 3.
Farch = 1000 kg / m ^ 3 * 9.8 m / s ^ 2 * 4 m * 0.3 m * 0.25 m / 3 = 980 N.
Answer: Farkh = 980 N.
