Lecture 1 - Driving forces

From the 1983 lecture programme:

The story of machines is almost as old as the story of man. One of the earliest engineers, the inventor of the wheel, set in motion much more than the load he transported from one place to another. Amongst his direct descendants, we can count the teams of engineers and scientists responsible for exploring space and those who are developing sensitive aids for the disabled. The driving forces behind these developments can be construed in two different ways. First there are the human factors, including a desire for new knowledge, a wish to improve matters and a sense of adventure. Then there are the actual physical forces that make things move. Curiously enough, we have only recently begun to understand their fundamental nature, and our knowledge is still incomplete. We shall look at this basis of motion. We shall also explore the ideas of kinematics that make up the geometry of motion. Such ideas form the basis of a large class of machines and machine elements, and, when forces are also taken into account, they make up the central ground of engineering design.
