The Lincoln Electric Case International Strategic Management By: Group 4A Introduction John C. Lincoln founded the Lincoln Electric Company in the year 1895. The first products that the company produced and sold were electric motors that he had designed himself. A Few years later‚ in 1907 his brother James‚ a recently graduate from the Ohio State University‚ joined as a senior manager; He was also the one who would introduce different and very innovative human resource policies

ELECTRIC DISCHARGE MACHINING INTRODUCTION * Sometimes it is referred to as spark machining‚ * Its a manufacturing process whereby a desired shape is obtained using electrical discharges (sparks). * Material is removed from the workpiece by a series of rapidly recurring current discharges between two electrodes‚ separated by a dielectric liquid and subject to an electric voltage. * One of the electrodes – ‘tool-electrode’ or ‘tool’ or ‘electrode’. * Other electrode - workpiece-electrode

current had produced a magnetic field strong enough to cause the compass needle to turn. Additional effects due to experiment * It was already known that an electric current in a wire has a heating effect‚ and may cause the wire to glow. This showed that the three phenomena of electricity‚ heat and light were connected. Experiment Apparatus Professor Ampere Andre Pierre Ampere’s Experiment * Ampère showed that two parallel wires carrying electric currents magnetically attract

The Physics of Rainbows As we are coming down to the final weeks of winter‚ the days are getting longer‚ and it is slowing starting to warm up. We are all looking forward to springtime‚ with its promises of flowers and rain. Along with this rain brings reminders of rainbows. As Donald Ahrens says in the Meteorology Today magazine‚ “rainbows are one of the most spectacular light shows observed on earth (About).” In fact‚ one of the best ways to view a rainbow at it’s utmost

LIGHT DEPENDENT RESISTANCE INTRODUCTION In the society‚ some times street lights glow in day time due to any reason. In mines area people face many difficulties due to absence of light in the nights. In frontier and hilly areas‚ people face many problems due to damaged street lights. For solve above these problems‚ we create a device in which the lights glow in night and in day time‚ they off automatically and don’t glow. Due to use of it‚ we can solve above problems and can also save electricity
