$2$PP Function Generation Analytical Synthesis: Design a $4-$bar function generator to

amplify an input angular motion. The input driver will rotate by $\backslash$beta $2$A $=30\backslash$deg while the

output $($follower$)$ rotates $\backslash$beta $2$B $=120\backslash$deg $(4$x the input angular displacement$).$

a$)$ Solve for the resulting four$-$bar linkage using the free choices below.

Free choices:

Wb$=4\mathrm{.}0$ mm $\backslash$angle $75\backslash$deg $,$ Wa$=2\mathrm{.}0$ mm $\backslash$angle $30\backslash$deg $,\backslash$alpha $2=45\backslash$deg

b$)$ Sketch the solution linkage to scale at both precision positions. Label all links

and pivots
