AI Thread Summary
To solve the problem of finding the tension in each wire supporting a uniform metal tube, it's essential to establish the points of moments and equilibrium. The tube is suspended by two wires at specific distances from the ends, creating a scenario where the forces must balance. Participants in the discussion suggest labeling the tensions as T1 and T2 to facilitate calculations. It is crucial to choose an appropriate pivot point for taking moments to simplify the analysis. Understanding the forces and their distribution is key to solving the problem effectively.

1. A uniform metal tube of length 5.0 m and mass 9.0 kg is suspended horizontally by two vertical wires attached at 50 cm and 150 cm respectively from the ends of the tube. Find the tension in each wire.


Okay, so I've sketched a diagram out and labelled it. The support would be somewhere between 90 and 120 cms as the forces would be even on both sides.
I am stuck on where to take moments from.

I don't understand this statement. What do you mean by 'the support'? What forces will be even?

Pick your favorite spot.

Hint: Label the tensions as T1 and T2. What equilibrium equations can you come up with?
 

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'

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...
