Question 23

In this question use g=9.8g = 9.8g=9.8 m s−2^{-2}−2.

A uniform rod AB AB\,AB of length 2.4 m and mass 6 kg is smoothly pivoted at the point CCC, where AC=0.9AC = 0.9AC=0.9 m.

A particle of mass m m\,m kg hangs from the rod at AAA, and the rod rests horizontally in equilibrium.

Find the value of mmm.
