    Forces Links
AI Thread Summary
The discussion focuses on understanding the forces acting on adjacent links in a chain under applied acceleration. Participants clarify that the problem requires calculating the forces between each pair of links, specifically between the 1st and 2nd, and the 2nd and 3rd links. The force calculation involves using the formula F=ma, with a mass of 100 g per link and considering the applied acceleration. A free body diagram is suggested to visualize the forces acting on each link. The conversation emphasizes the importance of recognizing contact points as links for accurate force analysis.

It means find the force between links that are next to each other. So what is the force between the 1st and 2nd link, the 2nd and 3rd link, etc.

Oh I supposed the points of contacts to be links. Thanks

The forces between 1st and 2nd would be (0.4)(9.8+2.5) applied by 2nd and the same by 1st. Am I right?

Is the force on 1st link = (0.5)(9.8+2.5)
 
According to the problem sketch, the mass of each link in the chain is 100 g.

Use this fact and draw a free body diagram of the forces acting on each link due to the applied acceleration.
