## Homework Statement

Problem image: https://prnt.sc/gvhjso

In this case I have to find the reaction forces at the point E (the Fx, Fy, and the Moment at point E) by using the given data. The 20kN forces at the load AC are concentrated, and are 1.8m far from each other. The tension of the cable is 150kN

## Homework Equations

Fx = Fcos( θ w/ respect to x-axis) or;

= Fsin( θ w/ respect to y-axis)

Fy = Fsin( θ w/ respect to x-axis) or;

= Fcos( θ w/ respect to y-axis)

Moment = Fd (where d is the perpendicular distance between the point of moment and the force)

## The Attempt at a Solution

This problem has the solution already given, which is this:

Now my problem is I do not understand why the solution did not include the force components at the BD part of the rope, only factoring the force components of the DF part of the rope/string. Why is it not included in solving the missing reaction forces at point E?
