The Figure shows a structure with relative dimensions as given, loading and materials indicated. The

horizontal member $abc$ is fixed at point $a,$ pin$-$jointed to the inclined member $eb$ at point $b$ and pin$-$

jointed to the vertical member $cd$ at $c.$ Find the following requirements:

a$.$ The appropriate type of element, DOF$/$node

and number of elements to model member eb$.$

b$.$ The reduced stiffness equation$($s$)$ for

member eb$.$

c$.$ The appropriate type of elem., DOF$/$node

and number of elements to model member

abc.

d$.$ The un$-$reduced global lumped load vector.

$($NB: identify reaction at nodes as $R_{nx}$ where

$R$ is the type of reaction, i$.$e$.,R$ or $M$;$n$ is the

node number; and $x$ is the coordinate

direction$)$

e$.$ The reduced stiffness equation$($s$)$ for

member abc.

f$.$ The reduced global stiffness matrix for the node at point$-$b$.$

g$.$ The consistent and lumped load vectors for beam abc.

h$.$ Solve for the displacements in the structure.

plz solve e$,$f $,$g and h only
