A frame is shown in the figure below, with points A and B are pin jointed, and point C is fixed. A load of 100 kN is applied at point B in the vertically downward direction. The Length of both the members AB and BC is 4m and the cross-sectional area of both the members are 100 mm2. E = 2 × 105 MPa and EI = 96 × 104 kNm2 Constant for all members, Then the reaction produced at support A is ______N.
