Principles of Simple Machines: Machines simply transmit mechanical work from one part of a device to another part. A machine produces force and controls the direction and the motion of force, but it cannot create energy. A machine's ability to do work is measured by two factors. These are (1) mechanical advantage and (2) efficiency. Mechanical advantage. In machines that transmit only mechanical energy, the ratio of the force exerted by the machine to the force applied to the machine is known as mechanical advantage.
The Rosicrucians are a mystical arcane society that played a major role in the development of Freemasonry. The rose and cross symbolize the society. It signifies crucifying the soul upon the body.
Rosicrucian manifestos opposed Roman Catholicism and its preference for dogma over empiricism, similar to texts authored by the Protestant Reformer Martin Luther. They traced their philosophy and science to the Moors, asserting that it had been kept secret for 120 years until the intellectual climate might receive it. Early seventeenth-century occult philosophers such as Michael Maier, Robert Fludd and Thomas Vaughan interested themselves in the Rosicrucian world view.
