A uniform beam AB AB\,AB has length 6 m and mass 10 kg. The beam rests horizontally on two supports X X\,X and YYY, where AX=2AX = 2AX=2 m and AY=5AY = 5AY=5 m.
Find the magnitude of the reactions of the support at X X\,X and YYY.
A block is now placed at A A\,A and the beam is on the point of tilting about XXX. Find the weight of the block.
Find the magnitude of the reaction at XXX.
