In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.
A uniform rod AB AB\,AB has length 3 m and mass 4 kg. The rod rests horizontally in equilibrium on two supports at C C\,C and DDD, where AC=0.5AC = 0.5AC=0.5 m and AD=2AD = 2AD=2 m.
Find the magnitude of the reaction of the support on the rod at C C\,C and the magnitude of the reaction of the support on the rod at DDD.
