An aerospace technician is investigating the buoyancy of a solid titanium component to be used in liquid fuel tanks. The technician is provided with a digital force meter (spring balance) and a deep tank filled with liquid nitrogen.
Describe how the technician should determine the upthrust acting on the titanium component when it is completely submerged in the liquid nitrogen.
