Q$2$: Based upon the diagram shown below, Mass $M1$ is hung from both Points A and $B$

and the segment between AB stays horizontal for both the loaded and unloaded

conditions. If the sag, $S=0\mathrm{.}75m,$ when the system is loaded, determine the tension in

segment $AB,AC,$ and $AD$ when the masses are applied. Lastly, what is $k_{AC}?$
