# Buoyancy and displaced volume
# Scope: Fully submerged body; constant fluid density.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

volume = 0.01 m^3
mass = 8 kg
density = 1000 kg/m^3
gravity = 9.81 m/s^2

buoyancy := density*volume*gravity [N]
netUpward := buoyancy-mass*gravity [N]

check positive buoyancy: netUpward >= 0 N

scenario alternative: volume = 0.008 m^3
