Homework Help Overview
The problem involves determining the forces acting on two light rigid rods, P and Q, which are hinged to a wall and support a weight W. The focus is on identifying which rod is in tension and which is in compression within the context of static equilibrium.
Discussion Character
- Exploratory, Conceptual clarification, Assumption checking
Approaches and Questions Raised
- Participants discuss the definitions of compression and tension, with some seeking clarification on the concepts. There are requests for hints and guidance on how to approach the problem, indicating uncertainty in applying static equilibrium principles.
Discussion Status
The discussion is ongoing, with participants expressing confusion and seeking hints to progress. Some guidance has been offered regarding the application of Newton's second law to the point where the rods meet, but no consensus or clear direction has emerged yet.
Contextual Notes
Participants are working under the constraints of a homework assignment, which may limit the amount of direct assistance they can receive. There is a focus on understanding the forces involved without providing complete solutions.

I can't think anything...
Actually, compression means the force towards the wall?
Can you give me some hints to start with the question...

"Compression" means that there's an inward force pushing on the ends of the rod; "tension" means there's an outward force on the rod.
This is a problem in static equilibrium.
This is a problem in static equilibrium.

Welcome to PF!
Hi tonald! Welcome to PF!
Hint: use good ol' Newton's second law on the peg (or whatever it is) where the two rods meet …
it isn't moving, and there are three forces on it, so they … ?
