Consider a uniform bar for which the center of gravity coincides with the geometrical center.
Weight of rod and length are $w$ and  $L$ respectively. Mark the correct statements about the rod.

Total gravitational torque about  $P$ may be considered as arising from a single force $w$ at the bar's center.

If a fulcrum is placed at $P$  the rod is balanced if $x = L/2$

Total gravitational torque about  $P$ may be considered as arising from a two individual forces of magnitudes  $\frac{wx}{L}$ and  $\frac{w(L+x)}{L}$  acting at the midpoints of the two segments defined by $P$.
