the relevance and effectiveness of the tittle "the crucible" as a metaphor for the situation depicted in the play.

the crucible(as in the vessel) represents Salem, itself; the piece of metal inside or whatever is being melted inside represents the people of Salem; the fire underneath the crucible represents the hysteria in the town; the pressure inside the crucible from the heat of the fire(hysteria) represents that accusations and the court

Please Help ASAP!! THANKS :)
