(engineering)
A general term for instruments which sample atmospheric suspensoids by impaction; such instruments consist of a housing which constrains the air flow past a sensitized sampling plate. Also known as impactometer.
(mechanical engineering)
A machine or part whose operating principle is striking blows.
(mining engineering)
