Question $3$Part AThe system is in equilibrium as shown. If the force F is $600$ N$,$ and the unstretched length of the cable AB is $3\mathrm{.}5$ m$,$Find the tensionTa in cable AB$.$ Express your answer to three significant figures and include the appropriate units.T$\_$BA $=$Part BFind the tensionTec in cable BC$.$ Express your answer to three significant figures and include the appropriate units.T$\_$BC $=$Part CFind the spring constant k in N$/$m$.$ Express your answer to three significant figures.k $=*$ First, draw FBD $($correct FBD earns up to $30\%$ credit$)*$ Second, build equations of equilibrium $($correct equations earns additional $40\%)*$ Third, solve the equations for unknows of interest $($correct solutions earns additional $30\%)$Please make sure you write these important components
