SUMMARY
The buoyant force acting on an aluminum cylinder suspended in an unknown fluid can be calculated using the difference in weight readings from a spring scale. The cylinder weighs 20N in air and 10N in the fluid, indicating a buoyant force of 10N. The relevant equation for buoyant force is Fb = pVg, where p is the fluid density, V is the displaced volume, and g is the acceleration due to gravity (9.8 m/s²). Understanding this concept is essential for solving problems related to buoyancy in fluid mechanics.
