By writing the forces as i the diagram forces, did the diagram, i don't care about the final answer and don't care about solving and finding the Miu, what i want to know is if the forces are right as the diagram or not, if not what is the problem, in other world i want to understand the physics...

The correct anser is Miu=0.25 My answer is 0.43.

Hi all, I have problem to solve this question: Wb=150N Wa=50N T=150N alph =? µ =? - There is friction between A and B only(Between A and the ramp there isn't). - A and B not moving(first Newton's law). 3. I tried to solve as: But the answer is wrong, can anyone help me please, and...
