$1\mathrm{.}1.$ For the continuous beam given in Figure $1,$ use Muller$-$Breslau$$s principles to construct the influence lines of the

following:

$1\mathrm{.}1\mathrm{.}1.$ Vertical reaction at support A

$1\mathrm{.}1\mathrm{.}2.$ Vertical reaction at support B

$1\mathrm{.}1\mathrm{.}3.$ Vertical reaction at support E

$1\mathrm{.}1\mathrm{.}4.$ Moment reaction at support F

$1\mathrm{.}1\mathrm{.}5.$ Shear force at point F$,$ which is $4$ m away from A

$1\mathrm{.}1\mathrm{.}6.$ Bending moment at point F
