It just makes intuitive sense for f(y) to be in the other direction (or negative). Like @A.T has pointed out, f(y) would be positive or...

Thank you all for clarifying my doubts! @A.T., especially, has given explanations with the most concise, understandable language without...

The arrow in the diagram just indicates the positive direction for a force component (sign convention), not the actual force direction...

In your examples the connections must transmit a torque. In the solution given by @kuruman they are assumed to be torque free. Based on...

I still think F(y) must be in the other direction

My doubt has finally been clarified, but for the sake of physics debate and to ensure i have no knowledge gaps, i am not fully convinced...

The pieces finally fit now! I understand that D is the true physical effect of the diagonal rod's force, we only choose to resolve the...

Its starting to make sense now. But i still don't understand why we don't consider the physical effects of force D on the horizontal...

Thank you all for your replies. I must apologize for the mild ambiguity in my query. I do know that force F results in a moment about...

Hey there, Before i introduce you to the question, i would like to clarify that this is not a home work question so i encourage all...
