The machine shown is used to help load luggage into airliners. The combined mass of the conveyor and luggage is $185$ kg with mass center at G$.$ Determine and plot the force in the hydruaulic cylinder BC $($report your answer as a positive value$)$ as a function of $$ over the range $336,$ then answer the questions.

Assume $\frac{?}{\text{b}\text{a}\text{r}}(DE)=1870mm\frac{,}{b}ar(CD)=1090mm,c=1590mm,d=1030mm,e=590mm,f=2040mm.$

Questions:

If $=11,BC=$ N

If $=21,BC=$ N

Over this range, the maximum value for $BC=$ N and occurs when $=$
