What is the Coefficient of Friction for a Pulley System on an Incline?

AI Thread Summary
The discussion focuses on calculating the coefficient of friction for a pulley system with two blocks on an incline and one hanging block. The known coefficient of friction for the block on the ramp (m1) is 0.15, while the coefficient for the second block (m2) is unknown. To determine the unknown coefficient, participants suggest using the forces acting on the blocks, including the acceleration of the system, which is given as 1 m/s². Additionally, the tension in the wire connecting m1 and m2 needs to be calculated while the blocks are accelerating. The conversation highlights the importance of understanding the forces involved to solve the problem effectively.

Three blocks are attached by a massless wire. Two blocks are on the incline, and the other is hanging below. The pulley is frictionless; however, the coefficent of friction between the ramp m1 is 0.15. The coefficient of friction between m2 and and the ramp is uknown.

A) Determine the coefficent of friction between m2 and the ramp of the acceleration of the system is m/s^2

B) What is the tension in the wire between m1 and m2 while the blocks are accelerating





I have spent many hours trying to figure out were to start. Would you use the force of m3 and the acting force of m2+m3 to determine the coefficent of friction?

You left out the (given?) acceleration of the system.
 
WOW- sorry bought that- was doing it quickly... it was if the system accelerates at 1 m/s^2
 

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'

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...
