As indicated by the math, the main benefit of machines is that they allow us to do the same amount of work by applying a smaller amount of force over a greater distance.
(the main benefit of machines; is; that they allow us to do the same amount of work by applying a smaller amount of force over a greater distance) Context(the main benefit of machines is,List([26, 57))):(they; allow; us to do the same amount of work by applying a smaller amount of force over a greater distance) Context(the main benefit of machines is they allow,List([26, 73))):(us; to do; the same amount of work)
the main benefit of machines is,List([26, 57)) the main benefit of machines is they allow,List([26, 73))
the main benefit of machines they us
is allow to do
that they allow us to do the same amount of work by applying a smaller amount of force over a greater distance
us to do the same amount of work by applying a smaller amount of force over a greater distance
the same amount of work
