Determine the weight and location (xc, yc) of the center of gravity G of the concrete retaining wall.

The wall has a length L, and concrete has a specific gravity of γ.

Units Used:

kip = 103 lb

Given:

a = 12 ft f = 1 ft

b = 9 ft g = 2 ft

c = 1.5 ft L = 10 ft

d = 5.5 ft γ = 150lb/ft3

e = 1.5 ft
