As you will see I know nothing about physics and after being asked to solve a physics problem in a recent interview wanted to ask it of professionals and see what the response would be:
I have a set of domestic scales (actually just one scale) that weigh up to the maximum weight of 5kg and a large package that weighs more than 5kgs but less than 10kgs. How can I tell the exact weight using the inadequate scales.
The package is a long item akin to a steal girder but not in weight obviously.
I know that stack exchange has rules about this type of question so please treat it as light entertainment from someone in awe of your intellect.
