Finding density of fluid from a mass on a spring in fluid

Click For Summary
SUMMARY

The discussion focuses on calculating the density of a fluid using a mass on a spring submerged in that fluid. The user determined the spring's length to be 1.039 meters and calculated the force acting on the spring to be 4.3 Newtons, which they identified as the buoyant force. However, the calculated density was found to be incorrect. The conversation highlights the importance of correctly categorizing homework questions to attract appropriate assistance from knowledgeable users.

PREREQUISITES
  • Understanding of buoyant force principles in fluid mechanics
  • Knowledge of Hooke's Law and spring constants
  • Familiarity with basic algebra for solving equations
  • Ability to interpret and analyze physics problems
NEXT STEPS
  • Review the principles of buoyancy and Archimedes' principle
  • Study Hooke's Law and its application in spring systems
  • Learn how to accurately calculate fluid density from buoyant forces
  • Explore common mistakes in physics problem-solving and how to avoid them
USEFUL FOR

Students in introductory physics courses, educators teaching fluid mechanics, and anyone involved in experimental physics or engineering applications related to buoyancy and density calculations.

When setting up the sum of forces I had an unknown value for the spring, buoyancy, and normal force. What I tried was setting up a triangle to find the length of the spring, which was 1.039m with that I could find the force acting on the spring, 4.3N, which would be the buoyant force I believe, but when plugging it into find the density my answer is higher than the right answer.

We ask the users here at PF try to post their HW questions in the appropriate subject forum, which is why your thread appears now in the Introductory Physics HW Forum rather than the Pre-Calculus Mathematics HW Forum. Proper placement of these threads will help you get more users looking at your thread and trying to help.
 
Thought that was the right one sorry.
