$$

Using the simplified riser design method; $($i$)$ You are requested to design proper risering system that will produce sound casting of the shapes shown in the figur$$ assuming $\backslash (\backslash$mathrm$\{$H$\}\_\{\backslash$mathrm$\{$T$\}\}=\backslash$beta $\backslash$mathrm$\{$D$\}\_\{\backslash$mathrm$\{$t$\}\}\backslash ),$

$($ii$)$ If the casting solidifies in about $8$ minutes, what is the solidification time of the riser;

$($iii$)$ Make a neat labled sketch of a section in the sand mold.

Dimensions are in inches
