About this app

Fourbar Linkage is designed to assist engineers and students in studying and analyzing fourbar linkage mechanisms. It provides a user-friendly interface that allows users to visualize the mechanism and explore its various characteristics.

Users can input the dimensions of the fourbar linkage, such as the lengths of the links, the coupler length and the angle respect to the connected bar, and observe how the mechanism moves and operates accordingly.

It helps identifying the singularities of the mechanism, in addition to the extremum transmission angles.

It also allows users to input specific angle for the crank position, enabling them to observe the resulting position of the linkage.
