Friction reduces the mechanical advantage (IMA) of a simple machine by causing energy losses in the form of heat. As friction increases, the effectiveness of the machine in transmitting force or lift decreases, ultimately lowering the mechanical advantage.
A perpetual motion machine is a hypothetical device that can continue to operate indefinitely without any external energy source. It violates the laws of thermodynamics, which state that energy cannot be created or destroyed, making the concept of a perpetual motion machine impossible.
Mechanical advantage is the term used to describe the ability of a machine to increase the output force. It represents the ratio of the output force to the input force in a machine. By utilizing mechanical advantage, machines can make it easier to perform tasks that would otherwise require more force.

The machine level.

standardization is important because it helps to determine whether the machine is set and working properly or not.
operator's manual is usually a book that describes all ( or most) the off functions of a machine and what the operator (or driver) needs to know to use then and how to keep the machine maintained.

It functions as a lever, with a fulcrum in the center.
