first lathe machine that was ever developed was the two-person lathe machine which was designed by the Egyptians in about 1300 BC. Primarily‚ there are two things that are achieved in this lathe machine set-up. The first is the turning of the wood working piece manually by a rope and the second is the cutting of shapes in the wood by the use of a sharp tool. As civilizations progressed‚ there have been constant modifications and improvements over the original two-person lathe machine‚ most importantly

Simple Machine Joemarie A. Martinez 1-D CE Simple machine Simple machines make work easier by multiplying‚ reducing‚ or changing the direction of a force. The scientific formula for work is w = f x d‚ or‚ work is equal to force multiplied by distance. Simple machines cannot change the amount of work done‚ but they can reduce the effort force that is required to do the work! As you can see by this formula‚ if the effort force is reduced‚ distance is increased. These simple machines fall

History of the Sewing Machine Before the sewing machine appeared‚ making clothes was the main occupation of half of the human race. For over 20‚000 years‚ countless hours were spent on making garments and other textiles to fulfill daily needs. The first sewing needles were made of bones and animal horns and the first thread was made of animal sinew (inventors.about.com‚ 4/16/06). The sewing machine‚ however‚ was a remarkable invention that was beneficial to all populations. More critical

Lathe Machine Turning is one of the most common of metal cutting operations. In turning‚ a workpiece is rotated about its axis as single-point cutting tools are fed into it‚ shearing away unwanted material and creating the desired part. Turning can occur on both external and internal surfaces to produce an axially-symmetrical contoured part. Parts ranging from pocket watch components to large diameter marine propeller shafts can be turned on a lathe. The capacity of a lathe is expressed

Special electric machines have a large field of application and actual requirements for electromechanical systems clam new and very performing solutions. There are a lot of papers on this subject‚ but anytime is mandatory to do something else to help users to develop high level systems. Main intention of the authors for this paper is to present a modality to analyze and to design a new solution of electric machine only trough finite element method. Actually‚ the users are asking for very performing

Generalization is the ability of a machine learning algorithm to perform accurately on new‚ unseen examples after training on a finite data set. The core objective of a learner is to generalize from its experience.[2] The training examples from its experience come from some generally unknown probability distribution and the learner has to extract from them something more general‚ something about that distribution‚ that allows it to produce useful answers in new cases.

MECHANISMS Definitions and Terminology 1. Introduction The subject Theory of Machines may be defined as that branch of Engineering-science‚ which deals with the study of relative motion between the various parts of a machine‚ and forces which act on them. The knowledge of this subject is very essential for an engineer in designing the various parts of a machine. 1.1 Sub-divisions of Theory of Machines The Theory of Machines may be sub-divided into the following four branches: 1. Kinematics
