    Confused
AI Thread Summary
The discussion centers on the confusion regarding the phrase "A is a factor of 3 above B." Participants clarify that typically, this means A equals B multiplied by 3, not 4. The conversation emphasizes that the context matters, but in common usage, the distinction is often overlooked. Comparisons are made to similar phrases, like "order of magnitude," to illustrate the point. Ultimately, the consensus leans towards interpreting the phrase as A being three times larger than B.

This is pretty urgent, I am really confused by this kind of wording.

Normally when people say A is a factor of 3 above B, do they mean A = B*3, or A = B*4?

Without seeing your particular context, I would normally take that to be approximately 3 times more than what it is compared to. As in 25 is about a factor of 3 times greater than 8.

Well in this context, there can be no approximate answer. So my question is really whether A is 3 times as large B or 4 times as large as B. This is more of an English question than math question.

My best guess then would be that it was 3 times and not 4.

It's comparable to saying something is an order of magnitude above. That is 70 is an order of magnitude greater than 7. It seems to me that someone would likely never mean that 77 was an order of magnitude above 7 and not 70.

I think most people in common usage don't make the distinction.
 
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...
