General Engineering Science in SI Units, Volume 2 covers the Engineering Science content of the General Course in Engineering, corresponding mainly to the requirements of the syllabus for the second year of a two-year course. This book discusses the resultant of a number of coplanar, concurrent forces; average velocity during uniformly accelerated motion; Newton's first law of motion; and graphical representation of the work done by a variable force. The load-extension graphs for brittle materials; coefficient of linear expansion of a solid; and electromotive force and potential difference are also elaborated. This publication likewise covers the magnetic effect of an electric current; rotation of a coil in a uniform magnetic field; and advantages and limitations of P.M.M.C. instruments. This volume is useful to students during the earlier years of CGLI Technician Courses and other engineering courses.
