DOING WORK WITH LESS EFFORT What comes to mind when you hear the word machine Do you imagine a shiny red racecar speeding around a track Maybe you picture a farmer on a muddy tractor plowing a farmer's field Or you might see a dishwasher and remember you are supposed to unload it The dishwasher does the cleaning but you still have to unload it 4
It doesn't matter if it is a car tractor dishwasher or something as simple as a ramp it is a machine if it helps you do work with less effort 5
