The Golden Crown of Hiero II, King of Syracuse Archimedes, 287-212 B.C. Hiero, 306-215 B.C. Hiero learned of a rumor that the goldsmith replaced some of the gold in his crown with silver. Hiero asked Archimedes to determine whether the crown was pure gold. Archimedes had to develop a nondestructive testing method

The Golden Crown of Hiero II, King of Syracuse The weight of the crown and nugget are the same in air: W c = ρ c V c = W n = n V n . If the crown is pure gold, c = n which means that the volumes must be the same, V c =V n . In water, the buoyancy force is B= H2O V. If the scale becomes unbalanced, this implies that the V c V n , which in turn means that the c n Goldsmith was shown to be a fraud!

Unformatted text preview: What is the best way to measure body fat? Hydrostatic Body-fat Testing using Archimedes Principle! Process Measure body weight W= body V Get in tank, expel all air, and measure apparent weight W a Buoyancy force B = W-W a = H2O V. This permits computation of body volume. Body density can be computed body =W/V. Body fat can be computed from formulas. Hydrostatic Body-fat Testing in Air? Same methodology as Hydrostatic testing in water. What are the ramifications of using air? Density of air is 1/1000th of water. Temperature dependence of air. Measurement of small volumes. Used by NCAA Wrestling....
