SUMMARY

Complete energy transfer between coupled pendulums requires that both pendulums have equal masses. This condition arises from the nature of the coupled differential equations governing their motion, which can be simplified when the masses are equal. Assuming equal masses (m1 = m2) allows for an uncoupled system that is easier to analyze and integrate, as discussed in Landau's "Classical Mechanics".

PREREQUISITES
  • Understanding of coupled differential equations
  • Familiarity with classical mechanics principles
  • Knowledge of angular frequency concepts
  • Basic integration techniques in physics
NEXT STEPS
  • Study the derivation of coupled differential equations in classical mechanics
  • Explore the implications of mass ratios on energy transfer in oscillatory systems
  • Learn about the concept of angular frequencies in coupled oscillators
  • Read Landau's "Classical Mechanics" for deeper insights into energy transfer in pendulums
USEFUL FOR

Physics students, mechanical engineers, and anyone interested in the dynamics of coupled oscillatory systems will benefit from this discussion.

Why is it that the two pendulums must have equal masses if complete energy transfer is to take place, assuming the angular frequencies are commnesumerable.

I think that the problem is in the sets of differential equations you get, they are coupled, maybe assuming that m1=m2 you can get an uncoupled system easy to integrate. I may be wrong :(

i`ve did that calculus long ago----> see Landau Classical Mechanics i bet you'll find you're answer.
