Hello @HareJare ,

$\qquad$!​

In PF things go like so: you post your problem statement and your attempt at solution and you indicate where you are stuck. Then we try to help with hints and questions.

In this case: what have you learned that could help you with this problem ? Principles, formulas etc.

Well i learned about torque and to achieve equilibrium it has to be the same on the left of the torque point and to the right.

My problem with this question is i don't know how to deal with

I know what to do on the right.
Torque RIGHT = 500 * F
but the rest i am confused about

 

[BvU]

How big must F' on the left be to compensate for the weight of 120 N ?

[HareJare]

It had to be equal to 120 or am i wrong here?
