In computer aided design (CAD), solid models can be constructed using

Ceramics and glass are machined by

When assembled, the hole $$ \begin{array}{r} +0.030 \\ 30+0.000 \end{array} $$. mm and shaft $$ \begin{array}{r} +0.020 \\ 30-0.020 \end{array} $$ mm will result in

A liquid metal is poured in a mold cavity of size $200 \mathrm{~mm} \times 200 \mathrm{~mm} \times 200 \mathrm{~mm}$. The cooling is uniform in all directions with NO additional compensation for shrinkage. Considering the volumetric shrinkage during solidification and solid contraction as $7 \%$ and $8 \%$, respectively, the length of the cube edge after cooling down to the room temperature is ___________ mm (rounded off to 1 decimal place).
