SUMMARY

The discussion focuses on solving a biomechanics problem involving angular momentum and forces acting on joints, specifically the knee. The key equation presented is Fm = (Fn * Rw) / Rm, which relates the forces and distances from the knee joint. Participants emphasize the importance of identifying all forces and their respective distances to formulate a comprehensive equation that accounts for the interactions between these forces. The discussion highlights the necessity of understanding angular momentum in biomechanics for accurate problem-solving.

PREREQUISITES
  • Understanding of angular momentum in biomechanics

Homework Equations


Fm= (Fn*Rw)/Rm





The Attempt at a Solution



honestly i have no idea where to even start for this, the equation i gave is probably way off but as i said, i have no idea.

This seems an angular momentum (terminology might be lacking in me) problem as you have joints, weights and their respective distances from the joints.

First identify all Forces and thei respective distances from the main join (knee). All have a direction of pulling and cancel each other out, so one big equation will suffice.
