Homework Help: Castiglianos second theorem

  1. Mar 6, 2010 #1
    i recently learned castiglianos second theorem, and going over the lecture i tried to solve the following beam,

    001.jpg

    i know that this beam is statically determined and i can use statics to find Ay=ql MA=ql2/2

    but i wanted to use castiglianos second theorem, using 2 equations (angle and deflection at A is 0) with my unknowns being Ay and MA and got the wrong answers

    the answers i got fit the statically indetermined beam with supports (like at point A) at both ends.


    is it impossible to solve this beam (for A and MA) using castiglianos second theorem? or am i making a mistake somewhere?
