Please I tried for six hours to finish this seemingly easy problem yesterday I'm in dire need of help I've tried everything.

Heres the Problem:

Q: For the loading condition shown below, determin the force on bolt O knowing that the triangular bracket is held up by the fixed shelf on the lower part of the wall.

(The value of F, is F=550 Newtons not 55 as it may appear in the picture.)

also I eventually found that the correct answer is F total=1037 N, but I don't know how to determine it.

Then found fx=275N and fy=-476 N from the componetns of f

What I did was Sum the Moments first take the moment of O and the Moment of A, since B cannot support a moment I didnt have one there.

so sum of M = M of o + M of A

sum of M's= 312.5 NM = (fay x .4 m) - (Foy x .4m)

and the

sum of x's=Fox=275

sum of y's=Foy=Ay-476

which makes the components of F, Fx= -275 and fy=681, which results no where near 1037 N...

I did somethign wrong I dont know what please help!!!! thank you!!!!

any help is much appreciated!!!!!!!
