[her uses of the term Machine, see Machine (disambiguation) A machine is any mechanical or organic device that transmits or modifies energy to perform or assist in the performance of tasks. It normally requires some energy source ("input") and accomplishes some sort of work.People have used mechanisms and machines to amplify their abilities since before written records were available. Generally these devices decrease the amount of force required to do a given amount of work, alter the direction of the force, or transform one form of motion or energy into another.The mechanical advantage of a simple machine is the ratio between the force it exerts on the load, and the input force applied. This does not entirely describe the machine's performance, as force is required to overcome friction, as well. The mechanical efficiency of a machine is the ratio of the actual mechanical advantage (AMA) to the ideal mechanical advantage (IMA). Functioning physical machines are always less than 100fficient.

>For other uses, see Monkey (disambiguation). A monkey is any member of two of the three groupings of simian primates. These two groupings are the New World and Old World monkeys of which together there are nearly 200 species. Because of their similarity to monkeys, apes such as chimpanzees and gibbons are sometimes incorrectly called monkeys. Also, a few monkey species have the word "ape" in their common name. Because they are not a single coherent group, monkeys do not have any important characteristics that they all share and are not shared with the remaining group of simians, the apes.
