Vent here!
 
Physics news on Phys.org
A student recognizes Einstein in a train and asks: Excuse me, professor, but does New York stop by this train?
 
Well, this one made me laugh a lot more but I thought it might be too much for the first post.

What does a mathematician do about constipation?
He works it out with a pencil.
 
The second one got a laugh out of me XD
 
Two physics students bump into each other walking across campus. One of them is toting his shiny new bicycle along with him. His friend says, "Wow! I really like your new bike!" "Thanks. It was the strangest thing! I was walking across campus the other day and a beautiful young girl rode her bike up to me, got off, ripped off all her clothes, threw herself on the ground, and said 'Take whatever you want!'"
"Smart move," he replied. "There's no way her clothes would have fit you."

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...
