Coefficient of Static Friction (inclined)

AI Thread Summary
The discussion revolves around calculating the coefficient of static friction for a physics lab experiment involving a wooden block on an inclined board. The initial formula provided, µs = x/y, yielded an implausibly high value, prompting a reevaluation. Upon correcting the formula to µs = y/x, the calculated coefficient of static friction was found to be 0.28. Participants confirmed that the revised equation was accurate for determining static friction. The conversation highlights the importance of using the correct formula in physics experiments.

Hi. During the completion of a physics lab i came across a problem. The lab consisted of putting a wooden block (0.10kg) at the en of a wooded board (1.84m), then lifting the wooden block side up slowly, so that when the block began to slide, we could record the hight. The problem is finding the coefficient of static friction. The formula provided by the teacher was µs = x/y. Is this the correct formula? After trying it, the number came out to be 3 point something, much too large i supose, but when i divided the y by the x it came out to be 2.7. Am i just doing something wrong, or is the incorrect equation given? Thanks.

ms = 0.10kg
lboard = 1.84m
x = 1.77m
y = 0.49m



µs = x/y ??



x was calculated, turning the given formula around gave me the supposed correct answer.



Thanks

It looks correct to me.
 
K thx, this part of my assignment relies on your judgement...
 
Actually I'm sorry, I looked at the wrong equation. It should be y/x not x/y. I got .28
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
