Finding Forces Acting on Member ABE: A Conceptual Question

[ME_student]

Homework Statement

Find the components of all forces acting on member ABE.

Homework Equations

Equations I used are on attachment

The Attempt at a Solution

I found moments about E and F. My reaction at E is correct. I just have a conceptual question about the reaction at C.

The reaction is a external force or internal at C and is it at an angle circles on attachment or straight? I want to say an external force at an angle.

The Attempt at a Solution

I found moments about E and F. My reaction at E is correct. I just have a conceptual question about the reaction at C.

The reaction is a external force or internal at C and is it at an angle circles on attachment or straight? I want to say an external force at an angle.

Since C is a pin in a slot, I think the reaction there must be a force acting perpendicular to the side of the slot. Any force component acting tangentially will just cause the pin to slide up or down along the direction of the slot.

Yes, it is perpendicular to the side of the slot. I got it worked out., but now I am stuck on another part of the problem. I need to find Reaction Ax, Ex and Bx. On members ACF will there be a reaction that will occur where the slot is or does that need to go away? I am taking moments about F to try to get Reaction Ax but I don't obtain the right answer. THe answer is 2025N leftward
