Determine the expressions for the deflection and axial displacement for the following three cases: (i) unit displacement of B in the positive direction of x, (ii) unit displacement of B in the positive direction of y and (iii) unit anti-clockwise rotation at B. For each case, calculate the support reactions induced by the enforced displacement. Assume A, I and E are constant throughout.
