A heavy weight $M=435$kg hang by the rope and the weight balances by the rod of mass $m=85$kg and a cable. Consider cable and rope has no mass. System is at static equilibrium $a=1\mathrm{.}92\mathrm{m,\; b}=2\mathrm{.}54m.$

a$)$ Draw a free body diagram of beam?

b$)$ Find the tension of cable?

c$)$ Find the reaction force on rod at contact point to wall?
