Point $\backslash ($ A $\backslash )$ and point $\backslash ($ B $\backslash )$ are the edges of a cliff are $3$ m away from each other in the horizontal direction. Create a bridge using a truss structure such that it spans the distance between $\backslash ($ A $\backslash )$ and $\backslash ($ B $\backslash ).$

Requirements:

$1.$ The bridge is meant for traffic, thus there must be a straight line between $\backslash ($ A $\backslash )$ and $\backslash ($ B $\backslash ).$

$2.$ Use members that are at most $1$ m in length.

$3.$ Since the bridge is meant for traffic, assume a uniform distribution of $\backslash (250\backslash$mathrm$\{$kN$\}/\backslash$mathrm$\{$m$\}\backslash )$ acting on the bridge.

$4.$ For simplicity, replace the distribution with equal forces that are acting at each of the joints that are in a straght line i$.$e$.$ the members in requirement $\backslash$#$1.$

$5.$ Ignore weight of the members.

$6.$ Analyse the structure using Method of Joints or Method of Sections.

$7.$ Determine whether each member is in tension or compression.
