Calculating force between links in a chain

Click For Summary
SUMMARY

The discussion focuses on calculating the force exerted by link 3 on link 2 in a vertically lifted chain of five links, each with a mass of 0.145 kg and a constant acceleration of 2.6 m/s². The correct approach involves applying Newton's second law, F=ma, to determine the net force acting on link 2, which includes both the gravitational force and the force due to acceleration. The final calculation confirms that the force exerted by link 3 on link 2 is 1.57 N.

PREREQUISITES
  • Understanding of Newton's second law (F=ma)
  • Basic knowledge of free body diagrams
  • Concept of net force in a system with multiple objects
  • Familiarity with gravitational acceleration (9.8 m/s²)
NEXT STEPS
  • Study the application of Newton's laws in multi-body systems
  • Learn how to construct and analyze free body diagrams
  • Explore the concept of tension in chains and ropes
  • Investigate the effects of varying acceleration on force calculations
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in mechanics, particularly in understanding forces in multi-link systems.

A chain consisting of five links, each of mass 0.145 kg, is lifted vertically with a constant acceleration of a = 2.6 m/s2.
Consider the force link 3 exerts on link 2. (Chains are numbered 5 to 1 going down)


Find the magnitude of this force.


F=ma


I don't know what to consider to find the answer. I tried doing a free body diagram, but I don't know what forces to add on it.
I tried F=ma --> a=2.6 m/s^2 and m=.145 kg
That didn't work, so I tried adding the downward force F=ma --> a=9.8 m/s^2 and m= .145 kg and that didn't work either.
How do I proceed?
