Calculate what the dynamometer will show if you hang a weight of lead with a volume of 300 cm3 on it.

To determine the readings of the dynamometer when suspending a load of lead, we use the formula: P = m * g = ρc * V * g.

Constants and variables: ρc – lead density (ρc = 11300 kg / m3); V is the volume of the cargo (V = 300 cm3; in the SI system V = 300 * 10-6 m3); g – acceleration due to gravity (g ≈ 10m / s2).

Let’s calculate: P = ρc * V * g = 11300 * 300 * 10-6 * 10 = 33.9 N.

Answer: The dynamometer will show that carrying a load of lead is 33.9 N.
