The structure in Fig. 4 shows a rigid bent rod, which, is subjected to three concentrated forces as is shown in the illustration. The support at A is a fixed support. Determine the following: (a) The resultant moment at point A due to only the applied concentrated forces. (b) The resultant moment at point B due to only the applied concentrated forces. (c) Find the support reactions at support A. HINT: (a) and (b) are asking for the moments of the forces about a particular whilst (e) is asking fro the support moment reaction at the fixed support.
