Homework Help: Unit Load Method for curved determinate structure

  1. Feb 20, 2016 #1
    1. The problem statement, all variables and given/known data
    A uniform curved beam ABC of radius R is fixed at C and is free at end A, and carries a vertical load W at B, as shown in Fig. 3.2. Considering only bending action of W, derive expressions for the vertical and horizontal displacements as well as the rotation at end A in terms of W, R and flexural rigidity EI of the beam. Ignore the self-weight of the beam.

    Use unit load method, 1.  U * .

    2. Relevant equations
    I had uploaded the qns and solution provided, but there is one part where moment about AB =0 which i do not understand.

    3. The attempt at a solution
    I understand the whole solution except for one part, which is moment about AB for real load analysis.Why is it 0 and not WRcostheta? Thanks in advance : )
