Analysing Experimental Data (PHOTOS INCLUDED)

AI Thread Summary
The discussion revolves around a student's confusion regarding analyzing experimental data and creating a proportionality statement after plotting the data. The student has attempted interpolation for specific values but feels uncertain about the accuracy of their work. There is a request for assistance due to the lack of detailed guidance from the teacher. Additionally, the clarity of the images shared is criticized, prompting a suggestion to type out the question instead. The overall focus is on seeking help with data analysis and understanding the proportionality concept.

Homework Statement


http://img217.imageshack.us/my.php?image=dscf3381gv1.jpg2. The attempt at a solution

http://img113.imageshack.us/img113/6683/dscf3380tp0.jpg It's really confusing, and the teacher didn't really go too much indepth on how to work this, so far i plotted the data, i used interpolation to estimate the data for 0.03 cm and 0.06 cm,

how do i write the proportionality statement? it just starts getting really confusing and the work that I did is just a guess, can someone PLS PLS PLS help me!

Hi Lawcheehung! Welcome to PF! :smile:

Sorry, but you photos are blurred, and hurting my eyes. :cry:

Can you type the question, please? :wink:
 

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...
