An aluminum (E = 70 GPa) cantilever must carry an end load of 1.4 kN as shown. However, in this design, when the beam is loaded the end of the cantilever A has to have the same elevation as point C (i.e., the net deflection of A must be zero). A hydraulic jack may be used to raise point B to achieve this. Determine the amount that B should be raised and the reaction at B (when the load is applied and B has been raised). Do not consider the weight of the beam. The cross-section of the beam is half of an I-beam as shown. The properties given in the box below are for the whole Ibeam. The position of the centroid of the half-section (relative to the top of the section) is shown in the figure.
