Exam #$3$:

The normal strain in the $x$ direction at point $q$ on the surface of the beam is ${}_{}=-100{10}^{-6}.$ Assuming $E=29,000$ksi and

$u=0\mathrm{.}3$ determine:

A$.$ the applied load $P,$ report your answer in kips to two decimal places

B$.$ the shear strain, ${}_{xy},$ at point $q,$ report your answer in ${10}^{-6}$rads to two decimal places Hint: once you find $P$ computc the shear, then the shear stress at $q,$ and compute ${}_{xy}$ at $q$
