Homework Help: Statics - Finding Reaction at Supports

  1. Aug 23, 2012 #1
    Hey I'm just going over a past paper and I've lost the section of my notes RE this topic.

    I understand how to draw the free body diagram when there is a pin involved, but not when it is connected at 4 points, the fact that they're at an angle is not helping.

    Any help greatly appreciated, thanks in advance.

    I don't see the horizontal member to the right of X contributing any force. It can be removed to simplify your analysis.

    Been 30 years sinvce I did this but ...

    The lower supports are fixed so can point X be temporaily replaced by a fixed support? The 20kN load is therefore shared equally between the one support to the left and the temporary support at X. The vertical load on the temporary support X is then transfered down to two lower supports.
