AI Thread Summary
Questions based on the polygon law typically involve analyzing forces in equilibrium or calculating the resultant of multiple forces by connecting vectors head to tail. The polygon law is often applied in physics and engineering contexts, particularly in vector addition. Users are seeking examples or problems that illustrate these concepts, as they have found limited resources online. Clarification on the specific application of the polygon law is needed for more targeted assistance. Understanding these principles is crucial for solving related problems effectively.

Largely based on some of your previous threads, I would guess you are referring either to forces in equilibrium or to finding a resultant of forces by chaining arrows together, head to tail. Please confirm.
 

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...
