A typhoon weakened the streetlight's foundation to the point that it could no longer sustain the streetlight's rotation. A supporting bracket was installed just in time to save the structure from collapsing. An L-shaped RUZ, is supported by pin at Z. Symbolically, the bracket may be thought of as a bar with a pin connection at S and a pin support at W, but its orientation is uncertain. There is a weight of 100 N exerted at point R. In addition, let's assume that the 50kN weight of the lamp post is located at S for the sake of this study (in computations, consider the 50kN force to act at RUZ). 100 N R 20 U Find: a..
