A large, open tank filled with SAE 30 oil has three windows on one of the sides as shown below. Calculate: a. The distance (m) from the liquid surface to the centroid of each window's area b. The magnitude (kN) of the resultant force on each window c. The distance (m) from the liquid surface to the location where the resultant force acts for each window d. How would these values in a, b, and c change if the liquid was water? Don't recalculate, just explain if they would increase, decrease, or stay the same and why. 3m A 2m 2m H-O 3m C 1m 2m
