$10\mathrm{.}3-6.$ Determine the magnitude and direction of tip deflection in the cantilever beam shown $($Fig$.$ Problem $10\mathrm{.}2-9).$ Let $E=70$GPa and consider only flexural deformations.

Thickness $t$ is small and uniform. Axes $y$ and $z$ are centroidal. Ignore possible twisting of the beam about its axis.

$I_2=8\mathrm{.}4(1U^{\text{'}})m{m}^{\text{'}}$

$I_{y2}=-4\mathrm{.}8({10}^6)m{m}^4$
