A uniform rod $AE\,$ has length 3 m and mass 4 kg. The rod rests horizontally on supports at $C\,$ and $D$ , where $A C = 0.5$ m and $A D = 2$ m.

Figure for question 8

Find the magnitudes of the reactions at $C\,$ and $D$ .

A block is placed at $E\,$ and the rod is on the point of tilting about $D$ . Find the weight of the block.

Find the magnitude of the reaction at $D\,$ in this limiting position. Use $g = 9.8$ m s $^{-2}$ .
