So, these 2 blocks are connected by a rope. Aluminuim block is 2kg and copper is 6kg. They are kept in motionless state via some kind of mechanism on steel surface. θ is 30 degrees. I was given dynamic and static friction coefficient (Aluminium μs=0,61 i μd=0,47, Copper μs=0,53 i μd=0,36.
Question is will these blocks move after mechanism that keeps them motionless turns off and I have to calculate force of tension in the rope. Friction of that little pulley is 0.
Solution for rope tension is 10N.
The Attempt at a Solution
I found G1 and G2:
I also found G2x and G2y:
After that I calculated force of static and dynamic friction:
Unfortunately, this is as far as I got because I don't understand and don't know what to do next since I never had any problems with static friction.
I hope someone can help me out on this one :)
