2.1 Decompose a simple system such as a home appliance, bicycle, or toy into its assemblies,components, electrical circuits, and the like. Figures 2.3 and 2.11 will help.
2.2 For the device decomposed, list all the important features of one component.
2.3 Select a fastener from a catalog that meets these requirements:
¦ Can attach two pieces of 14-gauge sheet steel (0.075 in., 1.9 mm) together
¦ Is easy to fasten with a standard tool
¦ Can only be removed with special tools
¦ Can be removed without destroying either base materials or fastener
2.4 Sketch at least five ways to configure two passengers in a new four-wheeled commuter vehicle that you are designing.
2.5 You are a designer of diving boards. A simple model of your product is a cantilever beam.
You want to design a new board so that a 150-lb (67-kg) woman deflects the board 3 in.
(7.6 cm) when standing on the end. Parametrically vary the length, material, and thickness of the board to find five configurations that will meet the deflection criterion 2.6 Find five examples of mature designs. Also, find one mature design that has been recently redesigned. What pressures or new developments led to the change?
2.7 Describe your chair in each of the four languages at the three levels of abstraction, as was done with the bolt in Table 2.2.
