Learning Goal:

The two square cross sections shown below are each subjected to a vertical shear force, $V.$ The side length of each cross section is $s=8\mathrm{.}00$ in and the side length of the hollowed$-$out portion of the second cross section is $r=4\mathrm{.}00in.$ The maximum allowable shear stress in each member is ${}_{\text{m}\text{a}\text{x}}=22\mathrm{.}0$ksi.

Part A $-$ Moment of the area $A^{\text{'}}$ about the neutral axis of the solid square shaft

One of the first steps in analyzing the geometry of the solid square shaft is to determine the moment of the area $A\text{'}$ about the neutral axis of the entire cross section. This value is denoted by $Q.$ What is $Q?$

Express your answer to three significant figures and include appropriate units.
