The problem is i have 4 forces (200,150,100,50) so i need each force to be in a quadrant and to be in balance,
I've been 6 hours and I could not answer

intresting problem, what have you done?

Can you state the original full problem? You're not giving us much to go of off.
It has a circular table with four moving movements and a free ring in the
center, of negligible mass, similar to that shown in Figure 1.
Each dumbbell has a mass of 50, 100, 150 and 200 grams.
The objective is to locate the 4 weights distributed at different angles one in each
quadrant of the plane, so that the ring is fully centered.

I thought we weren't supposed to do your homework problems.
I'm gonna solve this for practice because I'm in the same class as you, OP

whew lad. did it. took longer than I thought, but i kept making retard mistakes

here's my work. first I tried it on an xy-plane using x & y components, but it was a nightmare solving for theta. so finally I decided to just draw 4 vectors to scale, estimate 1 angle (104 in the diagram), and use trig to solve for the other 3 angles. then I had to translate all 4 angles to an xy-plane
it's ok estimating the first angle, because the other angles change accordingly. also, I had to draw a few diamonds to get one with 4 vectors in different quadrants
Here is another completely unrelated fun problem for you guys.
Find a quadrilateral with side lengths 50,100,150,200

>being this much of a fucking brainlet
Really? 6 hours on this problem? You must be joking
It's literally just asking you to sum resultant vectors and make it such that the net sum would be 0
I proved the solutions and its fail :(
Ok, i dont use maths for this but the answer is this ( ._.) (The angles are in rad)

How could u pretend doing mathematics here ?

let's see your answer then, m80
