Solve the following :


Calculate the torque on the square plate of the previous problem if it rotates about a diagonal with the same angular acceleration.


M.I. of square plate about its diagonal



&\mathrm{I}=\frac{m a^{2}}{12} \\

&\tau=I \alpha \\

&=\frac{(0.12)(0.05)^{2}}{12}(0.2) \\

&=0.5 \times 10^{-5} \mathrm{~N}-\mathrm{m}
