Tension from Incline Plane: Only Measured in Horizontal Direction?

Click For Summary

Homework Help Overview

The discussion centers around the concept of tension in the context of an incline plane problem, specifically questioning the dimensionality of tension as described in a provided image. Participants are exploring whether tension is solely measured in the horizontal direction or if it also has a vertical component.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the assertion that tension can be derived only from the horizontal dimension, with some noting that tension has both horizontal and vertical components. There is a discussion about the implications of using a rotated axis for analyzing forces.

Discussion Status

The conversation is ongoing, with participants expressing confusion and seeking clarification on the nature of tension in relation to the incline. Some have noted the importance of understanding the components of tension, while others are attempting to reconcile differing interpretations of the problem.

Contextual Notes

There appears to be a misunderstanding regarding the representation of tension in the problem, particularly in how it relates to the axes used for analysis. The original poster and others are grappling with the implications of the definitions and components of tension as they relate to the incline plane setup.

Ok, so in the red box it says that the tension is obtained from the horizontal dimension. This seems very wrong to me. Could someone explain this to me? Isn't there tension in the vertical dimension?

Note that the x direction isn't horizontal, but along the slope. Only the known force of gravity
and the tension in the rope have a component in this direction.
 
Thanks for your time.
This is noted. Even with the rotated axis, T still has a vertical component.

What he seems to be implying is that tension is only the horizontal component of force T. This I'm finding hard to digest.

That isn't what he means. He means you can find the tension if you know the component in the x direction: T cos(theta)
