Investigations on Suitable Configurations for Optimum Four-Bar Mechanism Balancing of Crank Rocker Engine

For a system to obtain perfect balancing, its external forces such as shaking forces and shaking moments are needed to be either eliminated or reduce. In this paper, numerous design approaches are modelled that theoretically will eliminate the external forces. The main objective that had been iden...
