SUMMARY

The discussion focuses on calculating the tension in a string supporting a 6-inch aluminum cube submerged half in water and half in oil with a specific gravity (SG) of 0.85. Using Archimedes' Principle, participants are advised to calculate the volume of fluid displaced by the cube and the resultant buoyant forces acting on it. The specific weight of aluminum is noted as 0.100 lb/in³, which is crucial for determining the overall forces at play. The tension in the string can be derived from the balance of these forces.

PREREQUISITES
  • Understanding of Archimedes' Principle
  • Knowledge of buoyancy and fluid mechanics
  • Familiarity with specific weight and specific gravity concepts
  • Basic algebra for force calculations
NEXT STEPS
  • Calculate buoyant force using Archimedes' Principle
  • Learn about fluid displacement in different mediums
  • Explore the relationship between specific weight and buoyancy
  • Study tension in strings under varying loads
USEFUL FOR

Students in physics, engineers working with fluid dynamics, and anyone interested in solving buoyancy-related problems in real-world applications.

First of all, let me just say this site is amazing idea and second of all I look forward to Contributing

A cube 6.in on a side is made of aluminum heaving Specific weight of 0.100lb/in3. If the cube is suspended on a wire with half of the volume in water and the other half in oil SG= 0.85. What is the tension on the String.

I hope some can answer this pretty quick. Thank you

Do you know Archimede's Principle? Calculate the volume of the two fluids displaced by each part, and then figure the forces exerted by each fluid volume on the cube.
