What is the Acceleration and Tension in an Inclined Pulley System?

Click For Summary

Homework Help Overview

The discussion revolves around an inclined pulley system involving two masses, m1 and m2, with given values and an angle of inclination. The original poster seeks to find the acceleration and tension in the system, while also inquiring about the relevant formulas for solving the problem.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants suggest starting with free-body diagrams for each mass to analyze the forces acting on them. There are questions about how these diagrams will aid in solving for acceleration and tension, as well as discussions on resolving forces in different directions.

Discussion Status

Participants are actively engaging in the problem by suggesting methods to approach it, such as drawing free-body diagrams and resolving forces. There is a focus on understanding the setup and the relationships between the forces, but no consensus or resolution has been reached yet.

Contextual Notes

The problem is set in a frictionless environment, which may influence the forces acting on the masses. The original poster has not provided diagrams, and there is an emphasis on the need to clarify the direction of force resolution.

Start by drawing a free-body diagram for each mass.
The formula is ##\sum \vec{F} = m\vec{a}##

a little more help?
 
Have you ever drawn a free-body diagram before?

yes but how will that help me?

Once you have drawn each diagram (one per mass), you should resolve forces in some pair of directions (common ones are horizontal, vertical, parallel to slope, normal to slope - any two of those will do, but it's usual to pick an orthogonal pair). That should allow you to write down two equations of the form net force = mass * net acceleration for each.
Draw the diagrams, post either the diagrams or descriptions of ithem, say which ways you are resolving, and post the equations you get.
 
What haruspex said - draw a fbd and see.
