Q$8\mathrm{.}1\mathrm{.}2$ A $4m$ long continuous beam ABC is under a uniformly distributed load $q$ of $5k\frac{N}{m}$ over

the $BC$ region, as shown in Fig. $8\mathrm{.}1\mathrm{.}2.$ Determine the respective deflections at the middle of each

span, if the flexural rigidity $EI$ of the beam is $250{10}^{3}N{m}^2.$
