SUMMARY

The discussion focuses on calculating the reactions at point E and the force at point C in a statics problem involving members CDE. The participant struggles with determining the reaction at D without employing a force triangle, ultimately concluding that reaction D has both x and y components. The instructor clarifies that point B has a reaction in both x and y directions, while reaction D is perpendicular to the bar, which simplifies the analysis. The participant's approach involves summing forces in the y-direction, yielding a value of 10 kips.

The Attempt at a Solution


Okay so I am having a hard time figuring out how to obtain Reaction D without using a force triangle because that is what the solution uses. I took sum of the forces in y direction at the pipe and get 10kips but what about the x direction? RD is going to have both x and y components.

I've been working on the problem for awhile. I first analyzed that D has a reaction both in x and y, also assumed B has a reaction in the x and y direction making it more complicated... I emailed my instructor asked him what the problem was. He said B has a reaction Bx and D is a reaction perpendicular to the bar.
