Question $5(15)$

Just for fun, or $5$ marks, determine the unknown $2$D stress and strain components assuming E$=110$

GPa and $v=0\mathrm{.}20.$

a$.{}_x=5$MPa,${}_y=-20$MPa

Solve for ${}_x=,{}_y=?$

b$.{}_x=-0\mathrm{.}0002,{}_y=0\mathrm{.}0005$

Solve for ${}_x=,{}_y=$

c$.{}_{xy}=40$MPa

Solve for ${}_{xy}=?$

d$.{}_x=-5$MPa,${}_y=0,{}_{xy}=-15$MPa

Solve for ${}_x=,{}_y={}_{xy}=$

e$.{}_x=5$MPa,${}_x=-0\mathrm{.}0003$

Solve for ${}_y=,{}_y=$
