Representing distributed loads with singularity functions

  1. Oct 6, 2014 #1
    1. The problem statement, all variables and given/known data

    could someone explain why the terms in red represent the red distributed load in the attached diagram?

    2. Relevant equations

    3. The attempt at a solution
    the only term I think I understand is the -3<x-0>^0 but I'm not sure of the rest

    It's not clear from the attached image. There are no terms in red.

    In any event, you need to understand how the particular singularity function is defined. The link below is a slide show which has the definition of a singularity function and includes some examples of how distributed loads, etc. can be represented.

    I read the slides but I'm still confused about this kind of distributed load

    could you explain the contribution of each term?
