SUMMARY

The problem involves determining the maximum side length L of a cubical block that can rest stably on a fixed cylindrical drum with radius R. The discussion references problem 6.35 from the "Introduction to Mechanics" by Kleppner and Kolenkow. Key considerations include the block's center of mass and the support point when the block is displaced by an angle θ. Analyzing these factors is essential for establishing the conditions for stability.

PREREQUISITES
  • Understanding of mechanics, specifically stability and equilibrium concepts.
  • Familiarity with the geometry of cubes and cylinders.
  • Knowledge of center of mass calculations.
  • Basic trigonometry to analyze angles and displacements.
NEXT STEPS
  • Study the concept of static equilibrium in mechanics.
  • Learn about the center of mass and its role in stability analysis.
  • Explore the effects of angular displacement on stability in rigid bodies.
  • Review problem-solving techniques for mechanics problems in the "Introduction to Mechanics" by Kleppner and Kolenkow.
USEFUL FOR

Students studying mechanics, physics educators, and anyone interested in solving stability problems involving rigid bodies and geometric shapes.

Homework Statement


A cubical block of side L rests on a fixed cylindrical drum of radius R. Find the largest value of L for which the block is stable.

This is problem 6.35 from the Kleppner+Kolenkow Introduction to Mechanics book. I honestly have no clue where to even start on this problem. Anyone care to give me a hint?

Say you displace the block by an angle θ. Where's the support point? Where's the center of mass in relation to the support point?
