What Is the Coefficient of Static Friction on a 17 Degree Incline?

AI Thread Summary
To determine the coefficient of static friction on a 17-degree incline with a 1760 N force pulling a 266 kg load, the formula used is the maximum static friction force divided by the normal force. The normal force can be calculated based on the weight of the load and the incline angle. Participants in the discussion express interest in the problem and encourage sharing progress on calculations. The conversation emphasizes the importance of understanding the relationship between force, weight, and incline angle in calculating static friction. Engaging in such physics problems enhances comprehension of frictional forces in real-world applications.

1. A 1760 N force pulls a 266 lg load up a 17 degree incline. What is the coefficient of static friction between the load and the incline?



2. Coefficient of station friction = Force(Static)Max / Normal(supporting) force

Welcome to PF;
Cool question.
How far have you got with this?
 
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...
