The separating distance between hinges A and $C,$ mounted vertically, is $1\mathrm{.}5m$ being hinge $C$ is

over hinge A$.$ A $4\mathrm{.}5m$ bar stretches horizontally from joint B to hinge while a distinct bar BC is

connected to joint $B$ and hinge $C.$ If the structure supports a $100KN$ load at point $B,E=70$

GPa, and $A=4000m{m}^2,$ compute the horizontal and vertical deflection at $B.$
