Tension force on incline

  1. Feb 3, 2009 #1
    1. The problem statement, all variables and given/known data
    Find the tension in each cord (three cords) in the figure if the weight of the suspended object is 250 N. There are two systems
    System 1
    Cord A is 30 Degrees below horizontal on the left, Cord B is 45 degrees below Horizontal on the right. Cord C connects the other two cords to the 250 N mass
    System 2
    Cord A is 60 degrees to the right of vertical. Cord B is 45 degrees below horizontal. Cord C connects the other two cords to the 250 N masss
    2. Relevant equations
    I'm not really sure where to start this equation, thought it was T1/sin(30) but that's not it, and without that I'm not sure how to continue

    In general you know that if it is not accelerating, in this case not even moving, then the sum of the forces will net to 0.

    So draw a diagram and resolve the forces in the tensions into horizontal and vertical components.

    If nothing is moving, then the sum of the horizontal forces is 0, and likewise for the vertical.
