A uniform rod AB AB\,AB has length 3 m and mass 8 kg. The rod rests horizontally on two supports 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 reactions of the support at C C\,C and DDD.
A block is now placed at B B\,B and the rod is on the point of tilting about DDD. Find the weight of the block.
Find the magnitude of the reaction at DDD.
