$(50$ pt$)$ A composite laminate is composed of a certain fiber$-$matrix composition such that

E$1=10$E$2$ and v$12=0\mathrm{.}3.$ Laminate is composed of three layers such that the stacking sequence is

$[90$o

$/0$o

$/90$o

$].$ Laminate is subject to uniform edge bending moment Mx $($Nm$/$m$)$ as shown below.

Determine the percentage of the bending moment that is carried by the $0$o

and $90$o

plies. How

does the percentage change if the outer layers are $0$o

and the inner layer is $90$o

$?$ Note: Each ply

has equal thickness of t
