Why does it say 10N for answer then?

I don't think so... Fsf1=G1*μs=11.97N Friction is higher than tension force pulling left block so it shouldn't slip right ?

T=G2x-Fsf2=29.43-27=2.43N

Well max friction should be Fsf2=G2y*μs=27N right ?

Sorry, can you give me more info :). I have no idea were to start really.

I think I may figured it out but I'm not 100% sure. So, if T=G2x-Fdf2 then T=11.08N. But it's not 10N like it says it should be. Also, should I use static friction or dynamic friction for calculating tension ?

Homework Statement 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...

Never mind. I figured it out. Thanks !

In that case thanks for help. I guess there's just something wrong with the problem then.

There 2 forces and in the middle is tension force. Is there any way you can get 25s ?

I'll try to translate the problem one more time. Two objects (2kg and 3kg) are attached by a rope which can withstand maximum tension force of 350N. (I hope this part is clear) Forces are acting on objects and their intensity change with time F=kt, where k is constant (10 N/s). Calculate the...

Yes for both forces =kt. I have no idea really how to start. I know how to work out standard tension problems but this one is really difficult.

Middle one is Fz or tension force, left one is F1, right one is F2. In the middle there is an x sign which is just representing breaking I guess.

Homework Statement Two objects (2kg and 3kg) are attached by a rope which can withstand maximum tension force of 350N. Forces acting on objects change with time (F=k*t) where k=10N/s. After how many seconds will rope break. Solution is 25s. 3. Attempt at the solution: I have tried...
