PROBLEM $4(20$ marks$)$

An axial centric force of magnitude $P=450kN$ is applied to the composite block shown by means of a rigid end plate. Knowing that $h=10mm,$ determine the normal stress in $($a$)$ the brass core, $($b$)$ the aluminum plates.

PROBLEM $5(20$ marks$)$

Two cylindrical rods, one of steel and the other of brass, are joined at

$C$ and restrained by rigid supports at A and $E.$ For the loading shown

and knowing that $E_s=200$GPa and $E_b=105$GPa, determine

$($a$)$ the reactions at A and $E,(b)$ the deflection of point $C.$
