How Does the Angle of Friction Relate to the Coefficient of Friction?

AI Thread Summary
The relationship between the coefficient of friction and the angle of friction is established through the concept of limiting equilibrium. The angle of friction is defined as the angle between the normal force and the resultant of the normal and friction forces. To prove this relationship, one can use basic trigonometry and draw a diagram to visualize the forces involved. As the angle of inclination increases, the friction force also changes, which is crucial for understanding how these two concepts are related. A clear understanding of these principles is essential for solving related physics problems.

Homework Statement


Just a proof that I am having touble with
State and prove the relationship between the coefficient of friction and the angle of friction


The Attempt at a Solution


I wouldn't know where to start, I know that
(the reaction force X coefficient of friction) = Friction force
And i would geuss that as the angle to the ground of something on the ground increased the friction force would increase. But I am not entirely sure how to prove or (or if I am beingf honest what I am proving)

any help would be greatly appreciated

By definition, the angle of friction is the angle between the normal force and the resultant of the normal and friction forces at limiting equilibrium. You'll need to draw a sketch and use some basic trig to find the relationship between the coefficient of friction and the angle of friction. (The angle of friction is the same as the angle of an incline at which point an object starts to slide).
 

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...
