Document Summary
Machine has three main functions multiply force change direction automate repetitive operations allow weak human to apply greater force or lesser/more precise force. 5 simple machines: machine can be one of these simple devices or combination of them (before greek era) Mechanic: works with and invents machines, or transforms machine to be suitable for purpose. Greeks in particular but also romans liked logic, deductive thought, things purely of the mind. Here you are entering into pure realm of physics and science. Machine reduces or multiplies force always center around human force and how to redirect or augment it. Mechanical advantage is a measure of the force amplification achieved by using a tool/machine factor by which the force needed to lift is reduced, Less force needed over correspondingly greater distance if facing something more than humanly possible can use machine to deal with force but need to exert it over greater distance.
