Construction for Two-Position Synthesis of a Four-Bar Linkage | Mechanical Design 101

The graphical construction of a four-bar linkage that coordinates two positions of an input crank with two positions of an output crank is presented in this video using Geogebra. A linkage that coordinates the values of input and output angles is called a function generator. It is possible to design a four-bar linkage to coordinate as many as five input and output angles. However, this requires numerical calculations using software such as our MechGen FG iOS application. Graphical Two Position Synthesis of a Four-bar linkage Function Generator.
