Question 10

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

Figure for question 8

Use $9.8\text{ m s}^{-2}$ .

Find the magnitude of the reaction at each support.

[3]

A block is placed at $B$ . The rod is now on the point of tilting about $D$ . Find the weight of the block.
