Problem $2.$ Rrob. $2$ :

Given ${}_1,$ find: ${}_2,b,c,d$ for enny $10$deg.

Loop closune:

$a_{+}{e}_{-}{d}_{-}{f}_{?}=0_{?}$

$a_{-}{b}_{+}{c}_{?}=0$

Algebraic equations:

acos${}_1+(2\mathrm{.}1-b)cos{}_2-d=0$

asin${}_1+(2\mathrm{.}1-b)sin{}_2-0\mathrm{.}7=0$

acos${}_1-$bcos${}_2=0$

asin${}_1-$bsin${}_2+c=0$

initially: ${}_1=\frac{}{4}$rad

${}_1^{}=-0\mathrm{.}2m\frac{d}{s}$

${}_1^{}=0$

Do porition analysis only.

for every $10$ crank rotation

$[$useprog$.3-10$ example and modity$]$

plot ${}_2,b,c,d$ vs$.{}_2$; and discuns reuelts

For the quick$-$return mechanism $($at the instant shown$)$:

${}_1=\frac{}{6}$rad

${}_1^{}=-0\mathrm{.}2ra\frac{d}{s}$

${}_1^{}=0$

Perform a complete position analysis

for this system for a complete revolution

of crank at each ${10}^0(\frac{}{18}$rad$).$
