Angle of rotation in fixed end of beam

  1. Jan 14, 2017 #1
    1. The problem statement, all variables and given/known data
    In the first photo , i was told that the fixed end moment is zero when the far end is pinned or roller supported . Why in the example in the second and third photo( both end are fixed) , the angle is zero ?

    2. Relevant equations


    3. The attempt at a solution
    I think it's wrong , because the fixed end must be able to resist shear force . In conjugate beam method , angle of rotation = shear force . So , as the fixed end can resist the moment , there must be some values for the angle if rotation , am i right ?

    Unfortunately your pictures are almost unreadable (and completely unreadable on a mobile device). Could we ask you to take a moment to generate your own images capturing the essential part of the problem?

    They seem to look better than when I first looked at them. Did you fix them?
