Pure bending moment

  1. Jan 3, 2015 #1
    i am trying to find the pure bending moment of this beam

    1. The problem statement, all variables and given/known data

    simply supported solid beam 3m long W=100mm D=200mm with a UDL of 2tonnes/m and a point load in the centre of 200N

    2. Relevant equations
    is the pure bending moment at the peak of the bending moment diagram
    i have calculated the reactions at the ends to be
    so 29,430*1.5/2=22,147 would this be the correct pure bending moment?

    Your reactions are correct. Your bending moment would be the sum of the maximum moments for the UDL and point load.

    Thanks what is the formula for this?

    I don't remember them off hand but they are readily available if you Google them. They're standard formulas based on the simple supports.
