AI Thread Summary
The discussion focuses on solving the equation Ro + 0.4Ro = 140, leading to the conclusion that Ro equals 100. The calculation steps include combining terms to get 1.4Ro = 140 and then dividing by 1.4 to isolate Ro. Participants confirm the correctness of the solution, noting the implicit coefficient of 1.0 in front of Ro. The clarity of the formula and the steps involved are emphasized for understanding. The final answer is verified as accurate.

1. I have a formula and for some reason can't grasp it



2. Ro + 0.4Ro = 140
Answer is Ro = 100



3. Ro + 0.4Ro = 140
1+0.4 Ro = 140
1.4 Ro = 140
140 / 1.4 = Ro

Is this correct

Yes.

There is an assumed 1.0 in front of the Ro.

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...
