Finding the Coefficient of Friction: A Simple Question on a 15 Degree Incline

AI Thread Summary
To find the coefficient of friction for a 100kg box on a 15-degree incline, one must consider the forces acting on the box at the threshold of motion. The box begins to slide precisely at this angle, indicating that the static friction force is equal to the component of gravitational force parallel to the incline. Participants emphasize the importance of showing previous work to receive assistance, as it helps identify any potential errors in calculations. The discussion highlights the necessity of using the homework template for clarity and organization. Properly addressing these points will facilitate a more effective resolution to the problem.

Okay, so here's the simple question...I just can't seem to figure out what I am doing wrong so I won't elaborate on what I have done or not done...


At the *second an incline rises to 15 degrees, the 100kg box on it begins to slide.

What is the coefficient of friction?

*Note: the box does not move until the incline HITS 15 degrees, no more, no less.


That is the problem verbatim.


Any help would be great!

Thank You!

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 hanged 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...
