Homework Help: Beam deflection question

  1. Sep 17, 2012 #1
    1. The problem statement, all variables and given/known data

    Find the maximum deflection in the beam.

    Beam breadth = 195mm
    UDL on beam: 40 Bar


    2. Relevant equations

    I have useed the method of superposition to try and solve it. Is this the best way?

    It has been suggested that finding the displacement by integration would give me a more accurate answer but I'm unsure how to apply it in this case.

    I am using Mechanics of Materials by R.C. Hibbler for reference.

    3. The attempt at a solution

    I = (bd3) / 12

    I = (0.195 x 0.053) / 12 = 2.03125x10-6

    Formula: y= (-5 x w L4) / (384 E I )

    y = (-5 x 4x106 x 0.1054) / (384 x 205x109 x 2.03125x10-6)

    y = 0.015mm

    Thanks for any help.
