Friction Force on Inclined Surface: How It Depends on Angle

AI Thread Summary
The friction force on an inclined surface depends on the angle of the incline due to the relationship between the normal force and the gravitational force acting on the body. As the angle increases, the normal force decreases, which subsequently reduces the friction force. A free body diagram is essential for visualizing these forces and understanding their interactions. The friction force is directly influenced by the coefficient of friction and the normal force, which varies with the incline angle. Analyzing these components provides clarity on how friction behaves on inclined surfaces.

Hi!
I have a simple question:
How does the friction force that acts on a body that is laying on an inclined surface depend on the angle of the surface?

Thanks.

You could draw a free body diagram and find out...:smile:
 
Specifically, you need to draw a free body diagram and resolve the forces. You will find that it is connected with reaction force, which in turn is related to the angle...
 

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...
