$C_2{C}_4=3cm$;$C_{2}A=2cm$;$C_{4}B=7cm$;$BD=10cm$; and $DE=8cm.$ Crank $2$ makes $45$ with the vertical and rotates at $100$ rpm $-$ counterclockwise. Block $3$ is fixed to Crank $2$ at $A,$ such that if crank $2$ rotates Block $3$ slides along Crank $4.$ Determine the linear velocity of block $6$ and pin $B$ in $c\frac{m}{m}in,$ also find the angular velocities of link $5$ and crank $4.k_s=1\mathrm{.}5$:$1,k_v=350c\frac{m}{m}in.$
