Dynamic force analysis- D’ Alembert’s principle –four bar mechanism- engine force analysis (reciprocating engines)- piston side thrust-connecting rod force-piston effort- dynamic force analysis considering mass of the connecting rod-analytical method. Flywheels-turning moment diagrams for four stroke internal combustion engine and multi cylinder engines-coefficient of fluctuation of speed-coefficient of fluctuation of energy design of flywheels.

Introduction- free vibration of single degree undamped systems- natural frequency-energy method- Newton’s second law (free body diagram)-damped systems- logarithmic decrement. Forced vibration-single degree of freedom systems-harmonic excitation-vibration isolation transmissibility-whirling of shafts

Introduction to two degree of freedom systems- natural frequencies and mode shapes. Introduction to design-definition, steps in the design process, materials and their properties- elastic and plastic behaviour of metals, ductile and brittle behaviour, shear, bending and torsional stresses, combined stresses, stress concentration factor.
