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?
>>
>>9144929
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

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

>>9144929
it's been awhile since I took undergrad physics but this looks like a very trivial torque problem, not fucking vectors
>>
I proved the solutions and its fail :(

Ok, i dont use maths for this but the answer is this ( ._.) (The angles are in rad)
>>
>>9145627
How could u pretend doing mathematics here ?
>>
>>9146340
let's see your answer then, m80
