Parametrically vary the length, material, and thicknessof the board to find five configurations that will meet the deflection criterion2.6 Find five examples of mature designs. Also, find one mature design that has been recentlyredesigned. 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 wasdone with the bolt in Table 2.2.
