$4.$ Use the Moment$-$arva method $($Mohr$\text{'}$s Theorems$)$ to determine, for the frame shown in Fig. Q$4,$

$($a$)$ the bending moment in the frame and

$($b$)$ the deflection at D $.$

Sketch the bending moment diagram giving the value of the bending moment at all salient points.

Sketch the deflected shape of the frame.

Take $EI=4000kN{m}^2$
