The book is comprised of 10 chapters that cover various aspects of mechanical sciences. The text first details the principles of stress-and-strain analysis and then proceeds to tackling the second moments of area of beam sections. Next, the book discusses combined direct and bending stresses. Chapter 4 talks about shear force and bending moment, while Chapter 5 deals with the slope and deflection of beams. The next chapters cover belt friction, velocity diagrams, flywheels, and oscillations. The last chapter discusses balancing rotating masses. The text will be of great use to mechanical engineers and technicians. Professionals dealing with machineries will also benefit from the book.
