Homework Help: Finding Theta

  1. Feb 22, 2010 #1
    Hi,

    When drawing the FBD (ex. block on incline), and when you split a force into x and y components, where do you put theta when giving the angle of let's say, the incline? Is there a trick to this? I generally know where to put it (basic trig), but for some reason I can't use trig for some other forces.

    Theta (or whatever you're calling the angle) would most likely be the angle the incline makes with the horizontal.
