How Does Archimedes' Principle Affect Damping in Harmonic Oscillations?

[InGolf]

Hi, I'm trying to build up a mass spring system, which is damp by a small steelball lowered into a buck containing soap mixture. Where the viscosity has been measured and we have calculated the flow arround the ball to be rather laminar (Reynold<1). But our data shows a damping around the double of our theoretical. My question is which influence will the Archimedes' principle of buoyancy have on our steelball and damping? Can the ekstra damping be explained by this force? And how will the buoyancy effect curve af the damp harmonic oscillation when it's only a force of one direktion..?

The buoyancy force is a result of the Archimedes' principle, which states that an object immersed in a fluid will experience a buoyant force equal to the weight of the fluid displaced. This force acts in a vertical direction, according to the direction of gravity. Since the steelball is lowered into a buck containing soap mixture, it will be subject to this buoyant force. The buoyancy force can increase the damping effect in the mass spring system due to the additional force acting on the steelball, resulting in a higher damping coefficient.The impact of the buoyancy force on the curve of harmonic oscillation will depend on the magnitude and direction of the force. If the force is pointing in the same direction as the oscillation, it will reduce the amplitude of the oscillations. However, if the force is pointing in the opposite direction, it will increase the amplitude of the oscillations.
