Intro to Mechanisms

CMU’s Introduction to Mechanisms

Yi Zhang, Susan Finger and Stephannie Behrens have prepared an on-line introduction to mechanisms consisting of eight chapters and almost 100 figures. Access it at the link:

Slider-crank analysis

Four-bar linkage analysis: Slider-crank

The slider-crank is an important mechanism with a wide range of applications. Here are my notes on its kinematic analysis.

Four-bar linkage analysis

Four-bar linkage analysis: 4R quadrilateral

The four-bar linkage is a basic machine component. It comes in two primary forms the 4R quadridlateral and the slider-crank. Here are my notes for the analysis of the 4R quadrilateral.

Chris Sangwin

C. J. Sangwin’s linkage movies

Chris Sangwin has a nice collection of linkage movies at How round is your circle?.

Particularly nice are the straight line mechanisms such as Hart’s second straight-line mechanism.

His example of the Sarrus linkage is also found on YouTube:

Fred Klingener has generated a number of interesting mechanism animations.  My favorite is the Peaucellier straight line mechanism.  You will find a table of 16 or so animations at his site:
