Answer 1

Answer #1

1. $FR heA$

h_c = vertical height of centroid = 18sin60 = 15.59ft

A = pi*(6)² = 113.1 ft²

F_R = 54.9x113.1x15.59 = 96.8 kilo pounds

2. differential element of force, $dF hdA$

Then the resultant force acting on the entire surface

$FR= d.A pdA hdA y18sin60$

F_R = 54.9x113.1x15.59 = 96.8 kilo pounds

2. A ground supported storage tank will be filled with 20 feet of crude oil with a unit weight of 52.4 pcf. Assume the empty tank structure plus its foundation weights 40 tons, and the tank diameter is 30 ft. Determine the induced stress caused by the full tank at depths of 15, 30, and 60 feet below the bottom of the tank (at the centerline). Use any method that you prefer.
