Uncertainty without a given estimation

AI Thread Summary
Calculating approximate uncertainty for a circle depends on whether the focus is on circumference or area. The uncertainty can be derived from the radius measurement, which should be clearly defined along with the method of measurement. For circumference, the formula is C = 2πr, while for area, it is A = πr². The precision of the radius measurement directly impacts the uncertainty in both calculations. Clear communication of the radius value and its measurement method is essential for accurate uncertainty estimation.

This is regarding a problem on approximate uncertainty. How do you just calculate an approxiate uncertainty of a circle when a radius is given?

What do you want for the circle; circumference or area?

And tell us exactly what you have been given for the radius, and how (if you have been told) the measurement for the radius was taken.
 

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...
