A sign ABCD is constructed from 7 mm thick plate steel (density p=8000 kg/m²) with the geometry shown in the figure. The sign is connected to the wall by a pin at A and also supported by member BE. Support member BE is also constructed from 7 mm thick plate steel and is connected by pins at B and E respectively. Determine the reaction forces at A and E. Enter your answers in Cartesian components. The weights of both the sign ABCD and member BE should be accounted for in the calculation.
