"Isi ike" na-ezo aka n'ike achọrọ maka mgbanwe otu ihe; "Ịgbanwe" na-ezo aka n'ọnụọgụ mgbanwe nke ihe n'okpuru ike otu. Ka "isi ike" ahụ na-ebu ibu, otú ahụ ka mgbanwe ahụ ga-adị obere; ka "ịgbanwe" ahụ na-abawanye, otú ahụ ka mgbanwe ahụ na-adịkwu mfe. Ihe nwere ezigbo ike dị nro, ogologo mgbatị ahụ na ike mgbawa na ike mmetụta na-abawanye, ebe ike siri ike, ike nrụgide na modulus elastic tensile dị obere.
Dịka a pụrụ ịhụ site na nkọwa dị n'elu, isi ike na ike dị iche iche, mana maka plastik emezigharịrị ha na-adabere n'otu. Dịka ọmụmaatụ, mgbe plastik fiberglass siri ike na-esikwu ike, ike nrụgide na ike mmetụta nwere ike ịbawanye.
Kedu otu esi eme ka ike plastik dịkwuo mma?
