Learning Outcomes

At the end of this course, the students;

construct the equation of motion of single degree of freedom mechanisms using kinematic influence coefficients and apply numerical methods to solve for equation of motion
perform force analysis in mechanisms including the effects of friction at prismatic and revolute joints
perform force analysis in simple and planetary gear trains and construct power flow diagrams
perform balancing of rotating machinery, design counterweights to obtain completely-balanced in-line four-bar mechanisms and reduce shaking forces and moments of in-line multi-cylinder engines
