The following measurements were recorded during compression test on two specimens: Mild steel and Cast Iron. The width and thickness of the specimen before the test are given in the table below (every dimension was measured three times) Cross-Section Steel Cast Iron Dimensions (mm) Measure #1 Measure #2 w= 12.66, t=12.67 w= 12.67, t=12.67 w= 12.67, t=12.67 w= 12.66, t=12.65 Measure #3 w- 12.68, t-12.67 w- 12.64, t=12.67 Calculate the average width (w) and thickness (t) in mm of both mild steel and cast- iron respectively. The order is w, t (mild steel), w, t (cast-iron) (Use two decimal places. do not add units, e.g. 10.02) With reference to data in question 17, what is the original cross section areas (Ao) of the mild steel and cast-iron respectively. (Use two decimal places, without units, e.g., 120.52)

(every dimension was measured three times)
Cross-Section
Dimensions (mm)
Steel
Cast Iron
Measure #1
w= 12.66, t=12.67
w= 12.67, t=12.67
Measure #2
w= 12.67, t-12.67
w= 12.66, t=12.65
Measure #3
w- 12.68, t-12.67
w- 12.64, t-12.67
Calculate the average width (w) and thickness (t) in mm of both mild steel and cast-
iron respectively.
The order is w, t (mild steel), w, t (cast-iron)
