$($a$)$ Indicate the practical travel length in relation to Beam AC

$($b$)$ Determine the tensile force in cable CD$,$ bending moment diagram and shear force diagram of the entire length of Beam AC when the weight W is at the mid span of Beam AC

$($c$)$ Determine the maximum tensile stress in cable CD which has the area of $0\mathrm{.}1$ m$2.$ what type of material would you choose to make the cable and why $($please provide reference to your justification$)?$

$($d$)$ Determine the maximum shear force, compression force and bending moment in Beam AC in relation to the location of the weight W
