363277 An object of mass \(8\;kg\) is hanging from one end of a uniform rod \(C D\) of mass \(2\;kg\) and length \(1\;m\) pivoted at its end \(C\) on a vertical wall as shown in figure. It is supported by a cable \(A B\) such that the system is in equilibrium. The tension in the cable is (Take \({g = 10\;m{\rm{/}}{s^2}}\))

363279 Figure shows a man of mass 50 \(kg\) standing on a light weighing machine kept in a box of mass 30 \(kg\). The box is hanging from a pulley fixed to the ceiling through a light rope, the other end of which is held by the man himself. If the man manages to keep the box at rest, the weight shown by the machine is
