AI Thread Summary

The discussion centers on the confusion regarding the calculation of moments for rigid bodies, specifically questioning the derivation of a particular definition of moment about a point. Participants express uncertainty about the distinction between vertical and perpendicular distances in the context of these calculations. The importance of understanding the correct distance to use in moment calculations is emphasized, as it impacts the accuracy of the results. Clarification is sought on what constitutes the "perpendicular" distance in this scenario. Overall, the conversation highlights the need for a clearer understanding of fundamental concepts in mechanics.

The underlined red part: I don't particularly understand where they got this from?
The yellow highlight: Why are they finding the vertical distance, instead of the perpendicular distance?

The underlined red part follows from the definition of moment about a point. In the yellow part, what would the "perpendicular" distance be?

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:
