    Mass Torque
AI Thread Summary
The mass of a suspended bar can be ignored in torque calculations when it is negligible compared to the weights hanging from it. Additionally, if the bar is suspended at its center, the mass is evenly distributed, which may also allow for its neglect in calculations. The discussion highlights the importance of comparing the bar's mass to other forces acting on it. Further conditions for ignoring the mass are not extensively covered. Understanding these principles is crucial for accurate torque analysis in physics problems.

Homework Statement



When analyzing the torques on a suspended bar such as meter stic, under what conditions is it acceptable to ignore the mass of the bar itself?

Homework Equations



NONE

The Attempt at a Solution



The only condition that I can find is when the mass of the bar itself is neg liable compared to the other hanging weights. Are there any more conditions that I am missing?

Would this work as well: if the bar was suspended in the center as the mass of the bar is equal on both sides of the suspension
 

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...
