I chose to study Mechanical Engineering because; they say it is the mother of all engineering. Be it Electrical engineering‚ chemical engineering‚ civil engineering without mechanical engineering all of this branches of engineering are useless. Our daily live is almost impossible to live without components that are made up of mechanical part. The pencil we use is been operated by the help of a simple mechanical design. All of these simple mechanical ideas have either made people rich‚ countries have
