Exam: Measuring the Coefficient of Friction

AI Thread Summary
To measure the coefficient of friction (μ), one common method involves using a force measuring device, such as a spring scale, to pull an object horizontally. This approach allows for calculating μ without needing to consider angles, as the force and mass provide the necessary data. Another method mentioned involves measuring the angle of incline (α) and using the formula μs = tan(α) to find static friction. The discussion seeks additional experimental ideas suitable for a university-level exam. Various techniques can yield accurate measurements of the coefficient of friction.

Hi everybody.
I am going to exam on Monday. I would like to make a experiment on how to measure the coefficient of friction.

I know, that I can find the mu(s), by taking the tan to the angle α.

μs = tan(α).

Is there somebody, who has some others ideas how to measure that? Somebody, who have done the experiment before. Maybe done it in a different way. It shall be university level.

I don't understand what experiment you are thinking of.
The usual way to measure μ is to use a force measuring device (spring scale?) to pull on an object. Knowing the force and the mass, you can figure out the μ. No angles involved if you pull horizontally.
 

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...
