Applicationem
Lamina ferrea resistens (abrasione resistens) lamina ferrea fortis est materias ferreas ad induendum resistentes, late in condicionibus operandis malis adhibitis, altae vires postulavit, summus wear-exactio resistens in machinatione, fodienda, constructione, agricultura, portu et machinatione metallurgica quaesivit. Solvendo igitur induendo et protrahendo vitam instrumentorum mechanicorum et componentium fit prima consideratio in desidendo, fabricando et utendo. Machinae onerariae, dredgers, currus omissi, invehentes plantas, TUBER aliquet, oras, cultri, confractores, comminutores, cribra, pastores, loculos mensurantes, ephemerides, situlas, anni, sphockets, oneratores aliquet, lorries, bulldozers, excavatores, slurry pipe systemata, cochleae traductores, torcularia etc.
