The square deforms into the position

shown by the dashed lines in $($

Figure $1).$ The dimensions are

$S=49mm,S^{\text{'}}=54mm,$

$x_1=2mm,$ and $x_2=9mm.$ Side

$D^{\text{'}}B\text{'}$ remains horizontal.

Part A

Determine the shear strain at A

relative to the $x,y$ axes.

Express your answer in radians to

three significant figures.

Part B

Determine the shear strain at $B$

relative to the $x,y$ axes.

Express your answer in radians to

three significant figures.

$({}_B{)}_{xy}=$

Part C

Determine the shear strain at $C$

relative to the $x,y$ axes.

Express your answer in radians to

three significant figures.

$({}_C{)}_{xy}=rad$

Part D

Determine the shear strain at $D$

relative to the $x,y$ axes.

Express your answer in radians to

three significant figures.

$({}_D{)}_{xy}=rad$
