This paper proposes a low‐cost technique for the evaluation of the forces in a kinematic mechanism of a slider crank system and provides these results for further use. By implementing the exact equations for kinematic and dynamic analysis in an object oriented programming module under the Visual Basic Net programming package, a theoretical dynamic simulation software was developed. All forces were extracted as graphical outputs on diagrams and as data tables, and are to be further applied as input files to Finite Element analysis systems for fatigue and stress analysis of a range of engine components.
