1 Introduction Welcome to Biomechanics Dr Dan Dudek North Cross School 1

2 Biomechanics What is biomechanics? 2

3 Some History Aristotle ( B. C.) De Motu Animalium (On the Movement of Animals) 3

4 Some History Leonardo da Vinci ( ) Mechanics of bird flight 4

5 Some History Galileo Galilei ( ) Discourses and Mathematical Demonstrations Relating to Two New Sciences 5

6 Some History 6

7 Rationale This course provides a fundamental understanding of the principles of locomotion: the questions we ask the experiments that may provide an answer the physical principles underlying the motion how nature has solved the problems of movement application of these principles to bioinspired devices 7
