A Honda in the frozen lake
We all know that in cold areas of the world people go fishing on frozen lakes. Instead of walking they sometimes drive their cars on the thick ice to the fishing-hole. And sometimes the ice brakes and the family sedans or big trucks land in the freezing water with a big splash.
It takes serious machinery to remove a car from a lake. One would preferably use a crane, but a crane is heavy, so there’s no way it would make it to the hole on the ice. Should you wait with recovery, in a few days the lake will freeze again and then you’ll have to let your car soak in the cold water of Lake Baikal till the temperatures rise. But if you have five men, a few logs and lots of rope, and know what simple machines are and how force and levers can help you to save your car, the problem will be solved within hours.
