    Forces Resolution
AI Thread Summary
Students often struggle with resolving forces and understanding force components due to a lack of clarity in foundational concepts. It's essential to ask specific questions about the aspects of force resolution that are confusing. Simply reiterating textbook explanations may not be helpful if the core misunderstanding persists. Providing detailed solutions to problems can help identify where errors occur. Engaging in targeted discussions can significantly improve comprehension and problem-solving skills in this area.

I am having a BIG problem regarding the resolution of forces and also component of forces .I just cannot simply understand it.I have v\been struggling with it ever since i studied it.Please help

We could explain and basically say the same thing they say in the textbooks, which you didn't understand so far. Or, you could ask specific questions about which part of a problem convcerning forces confuses you. If you think you understand it all but always turn out with the wrong answers to problems, post your detailed solution of one of them and we'll see where you've gone wrong.
 

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...
