Equilibrium: Solving the Homework Puzzle

AI Thread Summary
The discussion focuses on solving a homework problem related to equilibrium in a system of pipes. The user calculated the forces acting on both the top and bottom pipes, determining the normal forces at various points. Their results for the forces were 1387.344N for the top pipe and 4162.031N and 3924N for the bottom pipe. The user questions whether their calculations are correct or if the reference link contains an error. The conversation highlights the importance of verifying answers in physics problems involving equilibrium.

Homework Equations


Equilibrium - Fx = Fcos(theta), Fy = Fsin(theta)



The Attempt at a Solution


I've got the answer however it's different to the one posted the link above - isolated the top pipe and used equilibrium for the forces which were - normal force at C the weight W of the pipe and the force F exerted by the 2nd pipe. By doing this I found that F and C is 1387.344N. Then isolated the bottom pipe - forces present were - normal force at B and A, W and F exerted by 1st pipe. Did equilibrium and ended up with normal force at B = 4162.031N and normal force at A to be 3924N.
Did I do something wrong or is there an issue with the answer on the link?

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

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...
