Question $1(5$ points$)$

An elliptical trainer is shown in the figure with a corresponding schematic and vector

model defined. Also note key link parameters shown in the table. All Units are cm$,$

rad or ra$($d$)/($s$).$

Solve for Vgy$\_($ycomponent of velocity of point Q$).$ Point Q is at the midpoint of r $3.$

Enter values in c$($m$)/($s$).$ Assume that the input is link $2$ and the angular velocity of link $2$

is given $($omega$2$ or theta$2\_($d$)$ot$).$ Use the method covered in class.

Given data is here and on figure and table. r$1=150$;r$2$a$=106$; theta$\_(2)=1\mathrm{.}6057$;

omega$\_(2)=1\mathrm{.}3$;r$3=128$; theta $\_(3)=-0\mathrm{.}1746$;r$4=59$; theta $\_(4)=1\mathrm{.}4312$
