Review Questions

• How did Archimedes contribute to our understanding of buoyancy, and what practical applications did his discoveries have?
  • Archimedes contributed to the understanding of buoyancy through his principle that states a body submerged in fluid experiences an upward force equal to the weight of the fluid it displaces. This principle has practical applications in various fields, such as shipbuilding and fluid mechanics. His discoveries allowed engineers and scientists to design vessels that could float and navigate effectively in water by accounting for their weight and shape.
• Evaluate Archimedes' impact on mathematics and engineering during the Hellenistic period.
  • Archimedes had a profound impact on both mathematics and engineering during the Hellenistic period through his innovative ideas and inventions. He introduced concepts such as lever mechanics and developed methods for calculating areas and volumes that were advanced for his time.
