Problem writen on the pics.$($Situation $1)$ A joint between two concrete slabs A and $B$ is filled with a flexible epoxy that bonds securely to the concrete $($see figure$).$ The height of

the joint is in$.,$ its length is in$.,$ and its thickness is

vertically through the distance in$.$ relative to each other. Determine the average shear strain of the epoxy joint and the magnitude of

$V$ that should be applied to attain the said strain. Assume elastic behavior. The modulus of elasticity of the epoxy is $400$ksi and its Poisson's ratio is

$0\mathrm{.}45.(5$ points$)$
