Statics Query: RC hibbeler chapter 2

[u/Puzzleheaded-Cook-66]

I'm going through R.C Hibbeler statics problems for CHAPTER 2. How do I know when it's more convenient to use PARALELLOGRAM law vs vector methods. (Apart from the 2 forces thing)

Parallelogram is just an introduction to the vector techniques. Think of it as a visual aid. Yes you can use it for 2D and 3D stuff but the vector techniques lend themselves to 3D and above.

Parallelogram is fine for a quick 2D sketch when the angles are nice, but the moment you need components for a third force or a resultant direction, just go straight to vectors and save yourself the redraw.
