Izintengo zensimbi zanamuhla zihlala zizinzile. Ukusebenza kwekusasa elimnyama kwakungekuhle, futhi imakethe yamabala yahlala izinzile; ukuntuleka kwamandla e-kinetic akhishwe yisidingo esinqande amanani ukuthi aqhubeke nokukhuphuka. Izintengo zensimbi kulindeleke ukuthi zibe buthaka ngesikhathi esifushane.

Namuhla, intengo yemakethe ikhuphuka ngokuvumelana nenani eliqondisayo, isidingo siyantengantenga, amabhizinisi amaningi asemaholidini, amakhasimende anenkontileka athatha izimpahla ngokungananazi ngokwenani okuvunyelwene ngalo, futhi umsebenzi oyinhloko uwukunciphisa inani lempahla futhi adayise izimpahla. Kulindeleke ukuthi intengo yemakethe izinze.
