Abstract Friction stir processing (FSP) has been applied by several researchers to produce surface modification of metallic materials. The feasibility to produce TiC and B4C particle reinforced aluminum (AA6360) hybrid matrix composites (AHMCs) were studied in this paper. The measured content of TiC and B4C powders were compacted into a groove of 0.5 mm X 5 mm. Double pass FSP was carried out using a FSW tool at rotational speed of 1600 rpm, processing speed of 60 mm/min and axial force of 8 kN

ignition control, ventilation, segregation and identification. Proper segregation is necessary to prevent incompatible materials from inadvertently coming into contact. If incompatible materials were to come into contact, fire, explosion, violent reactions or toxic gases could result. When segregating chemicals, acids should not be stored with

will keep the egg from splitting in half from dropping. I also put some paper in it so that the egg will be more protected when it drops on the ground. This experiment relate to Newton’s second law which is the sum of forces equal mass x acceleration. The force that the egg hits the ground will equal the mass of the egg. It also relates to Newton’s third law which is for every action, there is an equal and opposite reaction. Whatever object the egg hits, a force will be exerted on the egg that is

more powerful by each passing day. One of these sciences is physics. Physics is science that concerns nature and the properties of matter. It includes mechanics, light, energy, magnetism, structure of atoms sounds and heat among others. The following paper is an essay concerning the use of physics in everyday activities. Skating, using cameras, warming homes using a woodstove, playing with balls that freely fall when suspended and using clothes during cold seasons are some of the examples of areas where

Isaac newton By Ethan Favour “We build too many walls and not enough bridges.” This was said by Sir Isaac Newton, who is credited for being one of the great minds of the 17th century scientific revolution. Isaac Newton was one of the most important and well known scientists in all of history. He was a mathematician and physicist and created several important inventions. Among his many great accomplishments, three significant things that made him well known were his laws of motion, his work

The friction, wear and acoustic emission behaviour of various combinations of alumina, silicon nitride, and SAE52100 steel, operating under dry sliding conditions, was investigated. A designed ball-on-flat-disc type of tribometer was used to conduct these experiments. This apparatus, equipped with a force sensor, using silicon strain gauges, measured simultaneously the normal load and friction force. Both forces were used to determine the real-time value of the dynamic coefficient of friction. The
