Virtual Work - Determining Relations

Click For Summary
SUMMARY

The discussion focuses on the mathematical relationship between delta A and delta C in the context of a rotating linkage system, specifically stating that delta C equals 4/9 delta A. The problem involves analyzing the changes in position at points A and C when linkage ABC rotates by a small angle δθ, with point B being fixed. The user seeks clarification on this relationship, indicating a need for a deeper understanding of the mechanics involved.

PREREQUISITES
  • Understanding of basic kinematics and rotational motion.
  • Familiarity with linkage systems and their components.

Thank you.
What change in position do you get at points A and C when linkage ABC rotates by a small angle δθ? Remember, point B is fixed.
