A$.$ Velocity Analysis by Numerical Method

For the below given four bar mechanism, The data is Link $1=6cm$;Link$2=2cm,$Link$3=7cm,$Link$4=9cm,{}_2=30,{}_2=10ra\frac{d}{s},R_{PA}=6cm,{}_3=30$

a$.$ Determine the velocities at point A and $B$

b$.$ Determine the angular velocities ${}_3$ and ${}_4$ and

c$.$ Find the velocity at point $P.$This is from theory of machine. Solve it by $(((($numerical method$))))$
