Dimension

AI Thread Summary

The discussion focuses on representing dimensions using the fundamental units of length (L), mass (M), and time (T). Participants explore how to express the dimensionless quantity "1" through various equations, such as 1 = 1s × 1Hz and 1 = 1 kg m/s × 1 s/kg m. The challenge lies in finding alternative representations that maintain dimensional consistency. The conversation emphasizes the complexity of dimensional analysis in physics. Overall, the thread seeks clarity on the mathematical relationships between dimensions.

As known,we can use 3 basic dimensions to represent other dimensions,but how to represent I with L,M,T?

Hello? Is there anyone could help me?

For example, 1 = 1s \times 1Hz = 1 \frac{s}{s} or 1 = 1 \frac{kg m}{s} \times 1\frac{s}{kg m}

I don't think there is another possibility ...

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
