Homework Help Overview

The discussion revolves around calculating the force on bolt O in a static equilibrium problem involving a triangular bracket supported by a fixed shelf. The original poster describes their attempts to analyze the forces and moments acting on the system, providing specific values and equations they have worked with.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to sum moments and forces to find the unknown force on bolt O but expresses confusion over their calculations and results. They mention specific values for forces and moments but are unsure where their reasoning went wrong. Other participants inquire about the relationships between forces and moments in the context of the problem.

Discussion Status

The discussion is ongoing, with the original poster seeking clarification and assistance on their calculations. Some participants are exploring different aspects of the problem, such as the force acting between points A and the hypotenuse of the triangle, indicating a variety of interpretations and approaches being considered.

Contextual Notes

The original poster notes a discrepancy in the value of the force F and expresses uncertainty about the correct approach to determine the total force on bolt O. There is an emphasis on the need for guidance without providing a complete solution.

Equilibium Of A Moment Help Please!

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:

I attached a diagram click statics to open it but here's the question
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 don't know what please help! thank you!
any help is much appreciated!

Can you determine the force act between A and the hipotenus of the triangle which is perpendicular to the hipotenus ?
