Question regarding Double cantilevered Beam

  1. Apr 6, 2009 #1
    I was just looking around for a formula for the deflection of a center-loaded beam that is cantilevered at both ends.

    For some reason my text does not have one. It does however have the deflection of a beam cantilevered at its end and I am thinking the two cases should be very similar if not identical, but I am having trouble rationalizing (or un-rationalizing) this.

    Can someone clue me in here?

    Oh! I just had a thought. I could use the formula for the center-loaded single cantilevered beam


    The formula for a an end-loaded cantilevered beam (opposite direction) whose end-load is equal to the reaction force of the other cantilever....

    I will play with this for a while.

    You can superimpose results. That is the way to go. However, one quick search did turn up this link:

    I believe you're looking at the third from the bottom.
