Question

If the lateral pressure at a certain height in a grain storage structure is calculated to be \(2000 \text{ kg}\cdot\text{m}^{-2}\); then the vertical pressure will be (given K = 0.5)

• A. \(1000 \text{ kg}\cdot\text{m}^{-2}\)
• B. \(2000 \text{ kg}\cdot\text{m}^{-2}\)
• C. \(4000 \text{ kg}\cdot\text{m}^{-2}\)
• D. \(1500 \text{ kg}\cdot\text{m}^{-2}\)

Hint:

Since the lateral pressure coefficient (\(K\)) is always less than 1 (typically ranging from 0.3 to 0.6 for grains), the lateral pressure is always less than the vertical pressure. This means the vertical pressure must be greater than 2000, which immediately rules out options (A), (B), and (D).

Answer 1

The Correct Option is C
