The simple machine I've found in my house is the SCISSORS. It makes use of the simple machine principle called ''lever''.It is used to cut things, from paper to meat. The fulcrum is found in the middle, and the effort is placed on the handle of the scissors. The load is then placed in between the blades. When an effort is applied to the scissors with a load on it, the sharp blades of the scissors will ''squeeze'' the load, causing the load to split. The amount used to cut a load varies according to the SIZE of the load , STRENGTH of it and SHARPNESS of the blade. Of course, if you try to take a pair of scissors to cut a COCONUT, then you should not expect the coconut to even have a single scratch on it. Also, if you use a 10 year old saftey scissors, then you should not even expect to cut CARDBOARD!!! The main difference between a pair of saftey siccors and a pair of metal scissors is that the saftey scissors are generally more blunt, and could not cut most hard materials like cardboard, whereas the metal scissors could cut most things, like hard cardboard, which the saftey scissors could not.
