Homework Help Overview
The problem involves a box-pulley system within an elevator, where the elevator is initially moving at a constant velocity and later accelerates downwards. The system consists of two blocks, A and B, with given masses, and the task is to calculate various forces acting on the blocks and the pulley.
Discussion Character
Approaches and Questions Raised
- The original poster attempts to calculate the tension in the rope and the forces acting on block A and the pulley. They express confusion about how to approach parts (b), (c), (d), and (e) of the problem.
- Some participants suggest drawing Free Body Diagrams (FBDs) for the components of the system to clarify the forces involved.
- There is discussion about the role of the tension in the rope and how it affects the pulley, with questions raised about the contributions of the rope to the forces acting on the pulley.
- Participants also explore the relationship between the forces acting on the blocks and the tension in the rope, particularly in the context of the elevator's acceleration.
Discussion Status
The discussion is ongoing, with some participants providing hints and guidance on how to approach the problem. The original poster has made some attempts and is seeking further clarification on specific parts of the problem. There is recognition of correct answers for parts (a) and (b), but uncertainty remains regarding the remaining parts.
Contextual Notes
The original poster is encouraged to show attempts for each part of the problem to receive more targeted help. There is an emphasis on understanding the underlying concepts rather than simply obtaining answers.
and I promise to have a free body diagram and my attempts written out beforehand when I come back.
