Question 1 (30 points): Anthropometric Design of a student chair In this exercise, you will identify the appropriate anthropometric measurement to assess the design parameters of a student chair for a classroom of mixed students (50% males and 50 %females). See Figure 1 below to check design parameters. B . 1 BH SW SH DH SD Figure 1 A student chair with the following design parameters: Seat height (SH), Seat width (SW), Seat depth (SD), Backrest height (BH), Backrest width (BW), Desktop height (DH). a) (9 points) Based on the anthropometric dimensions presented in the slides of Lecture 2, which anthropometric measurement is required for each design parameter mentioned in Figure 1 (SD, SH, SW, BH, BW, and DH)? Explain your answers. b) (12 points) For each anthropometric measurement identified in (a), which percentile(s) is (are) required for the adjustable seat design? Justify and explain in detail your answers
