Direction of Tension Forces

  1. Nov 25, 2007 #1
    Hi there,

    Im working on a problem where a portion of it deals with tension. When making a force diagram, I have a difficult time figuring out which direction the tension force is pointing.

    The problem looks like this:

    A block on an incline going downhill to the right, with a string attached and the string is attached to a wall on the left hand side.

    I want to say that the tension force is pointed down hill with the block, but it seems like I could talk myself into either way.

    Any help is appreciated! Thanks!

    Tension is in the string. Both ends of the string pull with equal magnitudes of force on the objects the string is attached to.

    Is the block stationary? I assume so. In that case, the tension is pulling the block with a force that will cause equilibrium.

    Yes, the block is stationary. Thank you very much!!
