Two blocks of mass $\displaystyle \mathrm{M}_1=20 \mathrm{~kg}$ and $\displaystyle \mathrm{M}_2=12 \mathrm{~kg}$ are connected by a metal rod of mass $\displaystyle 8$ kg. The system is pulled vertically up by applying a force of $\displaystyle 480$ N as shown. The tension at the mid-point of the rod is :
Official answer
(4)
$\displaystyle 192$ N
