QuestionProblem 2 ( 20 points). Determine the nominal maximum size for the coarse aggregate for the structural element in the figure. Select the appropriate commercial size for the coarse aggregate. \begin{tabular}{|c|c|c|c|c|c|c|} \hline & yestithation & & Bar Diameter [ing] & Bar Diameter [mm] & Cross-sertional Âpea (|in' \mid & \begin{tabular}{l} Cross- \\ Sectional Area \\ (mm²) \end{tabular} \\ \hline 43 & & 0376 & 0.735 & 9 925 & 011 & 71 \\ \hline H4 & & 0.658 & 0.5 & 127 & 02 & 129 \\ \hline 45 & & 1.043 & 0625 & 15975 & 0,31 & 200 \\ \hline 46 & & 1.502 & 0.75 & 1905 & 0,44 & 284 \\ \hline *7 & & 2.044 & 0875 & 22225 & 0.6 & 397 \\ \hline 48 & & 2.67 & 11 & 25.4 & 0.79 & 509 \\ \hline 49 & & 34 & 1428 & 2865 & 1. & 645 \\ \hline \#10 & & 4303 & 127 & 32.26 & 1.27 & 819 \\ \hline 11 & & 5.3135.313 & 141 & 3581 & 136 & 1006 \\ \hline *14 & & 7.65 & 1693 & 43 & 2.25 & 1452 \\ \hline \%18 & & 136 & 2257 & 57.33 & 4 & 2591 \\ \hline \end{tabular} - NMSmax =1/5=1 / 5 the narrowest dimension between sides of forms - NMSmax =3/4=3 / 4 clear spacing between rebars and between rebars and the form - NMSmax =1/3=1 / 3 depth of slabs

Studdy Solution
Select the appropriate commercial size for the coarse aggregate:
- The smallest NMSmax from the calculations is 1 inch. - Therefore, the nominal maximum size for the coarse aggregate should be 1 inch.
The nominal maximum size for the coarse aggregate is:
1 in \boxed{1 \text{ in}}
