They are not.fayan77 said:Pin A and C are the same
They are both pinned joints capable of taking forces in both the vertical and horizontal direction, but in this problem, no vertical force exists at C. You should attempt to answer the question asked by @mfb. What do you know about truss members with forces applied at joints?fayan77 said:they are tho, they look exactly the same. why is it that c does not provide a vertical force?
The Y component is not included in the solution manual because it is not relevant to the problem. The problem may only involve the X and Z components, so the solution manual only shows the equations and solutions for those components.
No, it is not a mistake. The solution manual is designed to show the solutions for the components that are relevant to the problem. If the Y component is not involved in the problem, it will not be included in the solution manual.
If you need to solve for the Y component, you can use the same principles and equations used for the X and Z components. You can also consult other resources or ask for assistance from a tutor or professor.
Yes, there may be cases where the Y component is relevant to the problem. It depends on the specific scenario and what is being analyzed. However, in the specific problem of Pin A & C, the Y component is not relevant.
It depends on the instructions and expectations of your exam. If the problem specifically asks for the Y component to be included, then you may lose points if you do not include it. However, if the problem only asks for the X and Z components, then you will not lose points for not including the Y component in your solution.
