Bush, "The Science of Penetration," The Streamlined Decade

1. Define laminar and turbulent flow. Which type of flow is equivalent to streamlined flow?

2. Cayley derives the ideal shape of an airship from what natural object?

3. Of the images shown in Chapter VII ("The Streamlined Moderne"), which of them demonstrate a relationship between structural forces and "streamlined" form?

Thompson, "On Form and Mechanical Efficiency," On Growth and Form

1. Thompson remarks that engineers often separate out tension from compression in order to "use separate modes of construction, or even different materials for each" (p.224). Would this tendency help or hinder a search for "tectonic" expression.

2. A section through a thigh-bone corresponds to the bone's moment diagram (p.227). Sketch a building structure, a part of a structure, or any other man-made object, in which form and moment-diagram also coincide. Comment.
