1 CHAPTER 1 INTRODUCTION The popular use of ball bearing for general industrial application can generally be associated with the late nineteenth century. With the increased usage and the increased sophistication of mechanical design came to necessity to predict their endurance capability. In this project an Effort has been put to analyze the deep groove ball bearing using finite element analysis the stress levels or displacement behavior of ball bearing. 1.1HARDNESS IN STEEL The

"Reactor control is achieved by means of 211 boron carbide absorber rods" (Mosey). The purpose of the rods is to absorb the excess electrons in the core and to control the rate in which the reaction is taking place. At Chernobyl nuclear fusion occurred by bombarding an isotope of Uranium 235 with an electron

NON TRADITIONAL MANUFACTURING PROCESSES- An overview Introduction Non-traditional manufacturing processes is defined as a group of processes that remove excess material by various techniques involving mechanical‚ thermal‚ electrical or chemical energy or combinations of these energies but do not use a sharp cutting tools as it needs to be used for traditional manufacturing processes. Extremely hard and brittle materials are difficult to machine by traditional machining processes such as turning
