Compute the net positive suction head available $(NPS{H}_A)$ for the following system: A $14-$in diameter pipeline runs from the suction tank to the pump is $69$ ft long and has a friction factor of $0\mathrm{.}025.$ The suction reservoir has an elevation of $2,018$ feet and the pump elevation is set at $2,008$ feet. The design flow rate is $3,417gpm.$ Assume minor losses of one rounded entrance, and one $90-$deg bend $($cast$/$forged$)$ and $T=100F.$ Round your final answer to the nearest foot.

$[10$ pts$]$ A vertical $4\mathrm{.}80$ kN load is applied as shown on a wooden post of rectangular cross section, $80120mm($see figure below$).$ Determine the stress at points A$,$ B$,$ C$,$ and D; show all work neatly.

Hint $1$: you'll have to combine $3$ stresses $($ from compression, $M_x$ and $M_z).$

Hint $2$: check your answer for ${}_D=+0\mathrm{.}375$MPa.
