Hi, having trouble determining the convention for determining the orientation of the principal axes.
(Please refer to the attached file for a diagram of my question)
So in Q1, theta = -19 degrees and the principal axes is rotated one of the following the conventions (from what I can tell)...
With respect to upper figure in the attached diagram, I don't really understand how the moment acts on the beam. I've always understood moments as forces that cause rotation and so when it is drawn as a straight line in the upper figure I'm not sure how that is affecting the beam.
With...
Hi all, please view the file I have attached which contains the diagram of the question. The picture is a cross section of a cantilever beam in which a force is applied downwards at the tip of the beam, as shown in the upper diagram. The solutions then conclude that the moment is acting in a...
