The slider-crank mechanism is a particular four-bar linkage configuration that exhibits both linear and rotational motion simultaneously. The position, velocity, acceleration and shaking forces generated by a slider-crank mechanism during operation can be determined analytically. The following report details the successful design, fabrication and testing of a pneumatically powered slider-crank mechanism for the purpose of classroom demonstration and experimentation. Transducers mounted to the mechanism record kinematic and dynamic force data during operation, which can then be compared to analytical values. The mechanism is capable of operating in balanced and unbalanced configurations so that the magnitude of shaking forces can be compared.
