VoyForums Announcement: Programming and providing support for this service has been a labor of love since 1997. We are one of the few services online who values our users' privacy, and have never sold your information. We have even fought hard to defend your privacy in legal cases; however, we've done it with almost no financial support -- paying out of pocket to continue providing the service. Due to the issues imposed on us by advertisers, we also stopped hosting most ads on the forums many years ago. We hope you appreciate our efforts.

”Vid en brand blir du tvungen att hoppa ut från ett fönster 5,0 meter över marken. När du landar så måste du böja på knäna för att klara landingen. Ett ben i kroppen tåler maximalt en belastning på ”170*10^6 N / m^2” alltså (hundrasjuttio multiplicerat med tio upphöjt till sex Newton per kvadratmeter) och ni kan utgå ifrån att kroppen rör sig 0,5 meter under träffen med golvet. Klarar du landningen med hela ben? (Uppgiften ska lösas teoretiskt. Jag vill inte ha några gipsade ben.)”
