← HistoryIn ancient China, which problem was reduced using clay-mold piece casting to produce crossbow trigger mechanisms?
A)Corrosion in varying soil chemistry
B)Dimensional inaccuracy between components✓
C)Brittleness under rapid cooling
D)Hydrogen embrittlement decreasing strength
💡 Explanation
Piece casting lowers dimensional inaccuracy because each mold section individually captures shape details. Therefore, each trigger component will have low deviation from the initial design, rather than compounding inaccuracies experienced in single block casting.
