The inventor of a new machine claims that its actual mechanical advantage is 4. literature on the machine reports its input distance is 81 meters and its output distance is 27 meters. find the machine's ideal mechanical advantage, and determine whether the developer's claim could be true.

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
