Simple Machines

      Trucks, railroads, and ships are machines used to haul goods. Without machines, the residents of our cities would find it more difficult to live, and farmers could not raise enough food to feed us. According to many experts without machines we would still be an agrarian society. Almost every activity of our daily life depends in some way on machines. We have 
constructed a wide variety of machines to satisfy our needs. Early people made stone axes that served as weapons and tools. The machines that were developed gave us great control over our environment. 
        A machine controls the direction and the motion of force. But it cannot create energy. A machine can never do more work than the energy put into it. In other words a machine can change the relationship between force and distance (work = F x d) but the total amount of work done is constant. It only transforms one form of energy such as electrical energy, to another form of energy, such as mechanical energy.
