Ukuqina okuqondile namandla okumunca amandla ezinsimbi zegwebu kuphakathi kokusetshenziswa okubalulekile kwezinsimbi zegwebu. Uhlu olukhulu lwe-modulus ye-elasticity lungatholakala ngokukhethwa kwemingcele yensimbi ye-foam, ukuze imvamisa yokuphendula oyifunayo ifaniswe futhi ukudlidliza okulimazayo okulimazayo kungacindezelwa futhi kuqedwe. Ukusetshenziswa okujwayelekile kokumuncwa kwamandla amabhafa kanye nezimunca ukushaqeka. Izinto ezisetshenziswayo zibuye zisetshenziswe kabanzi kumabhampa ezimoto, amabhafa amasistimu okuphakamisa nezokuthutha, ama-lining abamba amandla emishini, njll.
