Q$3.$ Consider the mechanism given below, The link $2$ drives the mechanism with an angular veloclty of ${}_2=10\frac{r}{s}CW,$ constant$).$

a$)(15$p$.)$ Compute the velocitles of all members for shown positions by using graphical relative velacity method.

b$)(20$p$.)$ Compute the accelerations of all members for shown positions by using graphical relatlve acceleration method.

$|)|)|)|{)}_x,$ Figure scale:$\frac{1}{1.}$

Strictly use the scale factors for the velocity as $25m\frac{m}{s}=1$ cm and the acceleration as $250m\frac{m}{s^2}=1cm$ for the proper use of paper.
