$(2$ points$)$ The system equations are given as

$m_1{x}_1^{}+b_1{x}_1^{}+k_1{x}_1=b_1{x}_2^{}$

$m_2{x}_2^{}+(b_1+b_2)x_2^{}+k_2{x}_2=b_1{x}_1^{}+u$

Use LT $($with zero IC assumption$)$ to draw the block diagram in $s-$domain for the given MIMO

system. Your block diagram must show TFs for $x_1,x_2,$ and $u$
