Singularity functions

  1. Sep 5, 2010 #1
    1. The problem statement, all variables and given/known data
    The beam in the picture is 16 inches long and support a is in the middle. I have to find the reactions R1 and R2 useig singularity functions. Unfortunatly i have no way on this computer to draw my FBD.


    3. The attempt at a solution
    q = -R1<x>-2-300<x>0+300<x-12>0-1000<x-16>-1+R2<x-8>-1


    now did i forget to put anything in this eqaution the only thing i can think of but am not sure is should there be a moment at O. The other thing I am unsure of is did i enter the part for the distrubuted load right.

    q = -R1<x>-2-300<x>0+300<x-12>0-1000<x-16>-1+R2<x-8>-1

    from here i should be able to integrate and solve for the rest just need to know if i have problems with my starting equation
