can any one tell me the components need for weigh scale
1 beam with a hole in the middle and one at each end.
2 hooks hang off the end holes
1 piece of string to go through the middle hole.
A couple of equal sized dishes with handles to hang on the hooks.
A set of pebbles of agreed weight (who do you agree with? That's up to you).
This system proved quite satisfactory from about 5000BC to 1800AD.
