AI Thread Summary
The discussion centers on analyzing a 4-link chain hanging by a rope, focusing on creating free body diagrams for each link and identifying Newton's third law pairs. Participants express uncertainty about how to begin the problem, particularly in visualizing the forces acting on each link. The task also requires ranking the magnitudes of these forces from smallest to largest, necessitating an application of both Newton's second and third laws. Understanding the interactions between the links and the tension in the rope is crucial for accurate analysis. Overall, the discussion emphasizes the importance of clear visualization and systematic reasoning in solving the problem.

Homework Statement



I don't have a picture of the diagram, but I'll do my best to describe it. A chain consisting of 4 identical links is hanging by a rope. The question wants to know what the free body diagrams would be for each link. It also wants all of the Newton's third law pairs to be identified, and it wants the rank, from smallest to largest, of the magnitudes of all forces (explaining the reasoning, including how Newton's 2nd and 3rd laws were used).

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
