Did I Make a Mistake in Solving for the Load Applied at Point D?

In summary, the speaker's answer was correct, but their approach differed from the textbook's method. They have checked their work multiple times but are still unsure of their mistake. They are seeking clarification on what went wrong. The speaker also mentions that they are not familiar with the textbook's method for the load applied at point D and that they used tangents instead of sin and cos to solve the problem, but their answer was still correct. They are unsure if the same approach will work for other similar cases.

Homework Statement
the 48-lb load can be moved along the line of action shown and applied at a, d, or e. determine the components of the reactions at b and f if the 48-lb load is applied at d
Relevant Equations
3 reaction equation
My answer was correct, however my direction was different from the textbook. I have checked my work a few times ,but not able to find out what I did wrong. Could anyone tell me what I did wrong.

Thank you in advance for your help.

I’m not sure what the textbook method was for the load applied at D. You somehow recognized that member ACF was a 2-force member. Otherwise the x and y components of the pin reactions at C and F would not be trigonometrically related . You should have used tangents instead of sin and cos, but nonetheless your answer is correct. What about the other cases? They may not give the same results.

FAQ: Did I Make a Mistake in Solving for the Load Applied at Point D?

What is the significance of point D in solving for the load applied?

Point D is a critical point in the load analysis as it represents the location where the load is being applied. It is important to accurately determine the load at this point in order to ensure the structural integrity and safety of the system.

How do I know if I made a mistake in solving for the load applied at point D?

If the load applied at point D does not align with the expected value based on the system's design and specifications, it is likely that a mistake was made in the calculation. It is important to review the calculations and double-check the input values to identify and correct any errors.

What factors can contribute to errors in solving for the load applied at point D?

There are several factors that can lead to errors in calculating the load at point D. These may include incorrect input values, mathematical errors, and assumptions that do not accurately reflect the real-world conditions of the system.

How can I ensure the accuracy of my calculation for the load applied at point D?

To ensure the accuracy of the load calculation, it is important to carefully review the input values and assumptions, use reliable and validated equations, and double-check the calculations. It can also be helpful to have a colleague or supervisor review the work for any potential errors.

What should I do if I find a mistake in my calculation for the load applied at point D?

If a mistake is identified in the calculation, it is important to correct it as soon as possible. This may involve revising the input values, recalculating the load, and re-evaluating the system's design to ensure its safety and functionality. It is also important to document the mistake and the corrective actions taken for future reference.
