Linear, simultaneous algebraic equations, ordinary differential equations, partial differential equations; and difference equations are the four most common types of equations encountered in engineering. This book provides methods for solving general equations of all four types and draws examples from the major branches of engineering. Problems illustrating electric circuit theory, linear systems, electromagnetic field theory, mechanics, bending of beams, buckling of columns, twisting of shafts, vibration, fluid flow, heat transfer, and mass transfer are included. Essential Engineering Equations is an excellent book for engineering students and professional engineers.
