SUMMARY

The discussion focuses on calculating the moment of inertia for a collection of point particles using the equations IH=(mCrC^2 + mHrH^2)x 2 and ID=(mCrC^2 + mDrH^2)x 2. Participants confirm the correctness of these equations and seek clarification on the next steps in the calculation process. The conversation emphasizes the importance of understanding the definitions of variables such as r_H and r_C in the context of the equations provided.

PREREQUISITES
  • Understanding of moment of inertia concepts
  • Familiarity with equations for point particles
  • Basic knowledge of mass distribution in physics
  • Ability to interpret variable definitions in mathematical equations
NEXT STEPS
  • Research the derivation of moment of inertia for point particles
  • Learn about the application of the parallel axis theorem
  • Explore examples of moment of inertia calculations in complex systems
  • Study the impact of mass distribution on rotational dynamics
USEFUL FOR

Students in physics, engineers working with rotational systems, and anyone interested in understanding the principles of moment of inertia calculations.

Homework Statement
From the moment of inertia of C2H2 and C2D2, I have to calculate the C≡C and C-H (C-D) bond lengths. I am confused on how to form the 2 simultaneous equations.
Relevant Equations
rH=
rC=
I really need help with this.

You need to at least show an attempt. What are the relevant equations?
 
Thank you for your reply. This is what I got so far but I am very unsure.
IH=(mCrC^2 + mHrH^2)x 2
ID=(mCrC^2+ mDrH^2)x 2

What is the moment of inertia for a collection of point particles in general? Does this match what you have written?

Edit: my apologies. I see from the picture in OP how you have defined ##r_H## and ##r_C##. Your moment of inertia equations are correct. What is the next step?
