4) ch14 DOE (design of experiment) The stopping distance of automobile is investigated against the carspeed, foot pedal power, and road surface roughness. By using the 2² factorial design a) calculated the magnitude of main effects a and interaction effects. 6) List three most important effects. method; Test Fun. 1 40 2 3 4 carspeed foot power surface stopping roughness distance (m - Âm tiep 8 - (30) -(50) -0.05) +60) -(50) -(0.05) 1-(30) +(100) -6.05). +(60) ico) -(0.05) 10 - (3) -(50) + (0.1) +(60) -(sol + (0.1) -(o) 100) +(60) +(00) + (0.1) 40 5 6 о BO 7 + (0.1) 50 2 c) find the cofficients for the following regression equation; (assume X, A, X 7B, C), ů Bot Bit + B2 X 2 + 837, +8, 2 X 12 7 Bahia +823 123 + $ 230,23 Where Bosū d) If car speed - 60 mph, foot and expected stopping distance is 54 ft; find the required surface roughness (in).
