Homework Help: Mass hanging on strings

  1. Sep 18, 2015 #1
    1. The problem statement, all variables and given/known data
    A weight is supported by 2 stings 1.3m and 2m long fastened to two points on a horizontal beam 2m apart. What is the depth of the weight below the beam?

    My question is- what does it mean by the "depth" of the beam?
    2. Relevant equations
    i'm new to the topic.

    3. The attempt at a solution
    the diagram which i made:
    please help in finding a solution. Thanks

    As I understand the problem, the weight is not a beam as you have drawn it but is, instead, small enough to be considered to be a point. The strings hang at angles to support it.

    I don't think your picture is right. Re-read the problem and try again.

    Also, you should write down the equilibrium conditions as the relevant equations.

    In which context did you get this homework or which cours are you attending? Because to me it seems, that you only have to calculate the distance of the weight from the beam - maybe for the center of the mass (which you have already found, but the force (vector) - if the drawn arrow should indicate this - points in the wrong direction).

    The new diagram should be like this then:

    no no! that arrow i have just drawn to label, it's not the direction of the vector.

    Yes, that's it.
