Position of Floating Cylindrical Disk in Water

Click For Summary
SUMMARY

The discussion centers on the physics of a floating cylindrical disk with a volume of 8.99 × 10-3 m3 and mass of 8.07 kg. The specific gravity of the disk is calculated to be 0.898. The participant successfully determined that the bottom surface of the disk is 1.27 cm below the water level. However, they are seeking assistance in calculating how far above the water level the top surface of the disk is positioned.

PREREQUISITES
  • Understanding of specific gravity calculations
  • Familiarity with buoyancy principles
  • Knowledge of volume and mass relationships in fluid mechanics
  • Basic algebra for solving equations related to floating objects
NEXT STEPS
  • Research Archimedes' principle and its application to floating objects
  • Learn how to calculate buoyant force and its relation to submerged volume
  • Study the relationship between density, volume, and mass in fluids
  • Explore the concept of hydrostatic pressure and its effects on floating bodies
USEFUL FOR

This discussion is beneficial for physics students, engineers, and anyone interested in fluid mechanics and the principles governing buoyancy and floating objects.

A cylindrical disk has volume 8.99 × 10-3 m3 and mass 8.07 kg. The disk is floating on the surface of some water with its flat surfaces horizontal. The area of each flat surface is 0.633m2. (a) What is the specific gravity of the disk? (b) How far below the water level is its bottom surface? (c) How far above the water level is its top surface?



I solved part a, which is .898, but i have no idea how to get b and c.
Like what equation would i use?

Please describe an attempt or describe what you know about the system, first. Anything. Then we help.
 
ok i actually just solved part b and got 1.27 cm.
kind of stuck on part c
