Find the force of Archimedes, acting in water on a cast iron workpiece with a volume of 0.2 m3.

The force of Archimedes, which acts on a cast-iron workpiece, is calculated by the formula:

Fa = ρ * g * V, where ρ is the value of the density of water (according to the condition ρ = 1000 kg / m3), g is the acceleration of gravity (const, g = 10 m / s2), V is the volume of the submerged part of the cast iron workpiece (cast iron the workpiece is completely immersed in water, V = 0.2 m3).

Let’s make a calculation:

Fa = ρ * g * V = 1000 * 10 * 0.2 = 2000 N = 2 kN.

Answer: Acting on a cast iron workpiece, the Archimedes force is 2 kN.
