Torque and Principle of Moments

Angular speed $\omega$ versus time$t$ for a rod that rotates around one end is shown. If moment of inertia of rod about its one end is $24 \mathrm{kg} {\mathrm{m}}^2$, then torque on the rod at $t=2 \mathrm{s}$ is

$ABC$ is an equilateral triangle with $O$ as its centre ${\overrightarrow{F}}_1,{\overrightarrow{F}}_2$ and ${\overrightarrow{F}}_3$. represent three forces acting along the sides $AB, BC$ and $AC$ respectively. If the total torque about $O$ is zero then the magnitude of $F_3$ is

Three massless straight rigid rods, each of length $L$ are rigidly joined to give shape as shown. Two particles each of mass $M$ are fixed at ends as shown. Whole system is free to rotate about a fixed axes passing through the cross section of middle rod as shown in fig. in a gravity free space. What is the net torque acting by the fixed axes on the whole system
