- Homework Statement
- Blocks A and B of mass 13 kg and 10 kg respectively, are placed on the inclined plane and released. The coefficients of kinetic friction between the blocks and the inclined plane are μA=0.2 and μB=0.5 . Neglect the mass of the link.

Determine the magnitude of the force developed in the link.

- Relevant Equations
- nothing special.

Do I determine this from the friction coefficients?

Such that because mu_b > mu_a I know that it'll push on B because it has a bigger friction coefficient.

such that this has nothing to do with the mass of the blocks? or does it?

f.e. can I take it to be in an arbitrary direction and then solve the equations of motion for both and find the magnitude of the force in the link that way?

I did it but I might've ran an error in the analysis. I did it the other way around aka looking at it as mu_b>mu_a such that it pushes B forward and A backwards and I got the correct answer.

appreciated.
