This paper presents Part II of a two-part investigation dealing with the damped elastic behavior of the counterweighted rocker link of a four-bar linkage which also carries an overhanging mass. The analytical techniques developed in Part I are applied to an example mechanism and the results are compared to those of an associated experiment. Three mode solutions of decoupled Hill’s equations furnish a stability analysis as well as steady state solutions for strain responses at off- and on-resonance locations over a range of speeds from 100 to 200 rpm. In general, good qualitative as well as quantitative agreement between analytical and experimental results was found.
