AI Thread Summary
When adding two vectors graphically, the correct methods include moving a vector and rotating a vector, but changing the length or angle of the vectors is not permissible. The discussion emphasizes the importance of sketching the vectors individually before combining them to visualize their addition accurately. Participants are encouraged to illustrate their vectors to better understand the graphical addition process. The conversation highlights the need for clarity in vector manipulation techniques. Overall, proper graphical representation is crucial for accurate vector addition.

Welcome to the PF.

Why do you say that?

Take two vectors, sketch them individually, and then sketch their addition. What did you do when you sketched their addition?

A = [1,1]
B = [2,3]
C = ? (sketch the answer...)
 

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...
