The discussion revolves around determining the tension force in blocks situated on an incline, focusing on the dynamics of the system involving multiple blocks connected by a rope. The subject area includes concepts from mechanics, specifically Newton's laws of motion and forces on inclined planes.
Some participants have suggested using substitution in their analysis and have begun to clarify the direction of forces acting on the blocks. There is an ongoing exploration of how to apply Newton's second law to the system, with acknowledgment that the blocks share the same acceleration due to their connection.
Participants are navigating the constraints of the problem, including the need to define forces accurately without assuming values, and the implications of the incline on the forces involved.
You cannot assume any value for the tension. Just call it "T" and include it in your analysis.sash187 said:
The blocks are connected by a rope, so they have the same acceleration.
That would work.sash187 said:
Both the tension and the friction force on block A act up along the incline (North East, if you like). I don't know what you mean by the 'MA force'. The acceleration is down the incline.
That's not a force, that's mass*acceleration. If you were to list the forces acting on either block, you would not include 'mass*acceleration'. That term appears when you apply Newton's 2nd law.sash187 said:
