## Homework Statement

Solve for the support reactions (at A and B) in the figure given.

(the pink thing is a cable and there's an arbitrary weight hung at the end of the cable).

## Homework Equations

sum of forces in y direction=0

sum of forces in x direction=0

Sum of moments =0

## The Attempt at a Solution

I tried solving this using the method of joints in TRUSSES. However, consider point A (JOINT A). Here, there's the vertical component of support reaction and no other vertical force to cancel this, so

**joint A is not in equilibrium.**

**Why does the method of joints not work in this case?**

My professor told me that Truss analysis doesn't work in structures that are not 2 force members...however, I find many contradictions to this.

Please give me a solution to this problem.
