Question
**Transcription for Educational Website** **Title: Understanding the Calculations for Area Ratio in Soil Sampling** **Description:** This educational text explains how to calculate the area ratio for a soil sampler and determine if the sample obtained is disturbed or undisturbed. **Diagram Details:** The figure illustrates a soil sampler with various components labeled: - **Water Port:** An entry point for water. - **Head and Pin:** Parts of the sampler’s structure. - **Drilling Rod and Coupling:** Connects the sampler to the machinery for drilling. - **Ball Valve:** A valve for controlling the flow within the sampler. - **Split Barrel:** The main body where the soil sample is collected. - **Threads Driving Shoe:** Used to penetrate the ground and guide the sample into the barrel. **Measurements:** - The sampler has specific dimensions: - **Exterior Length:** 457.2 mm (18 inches) - **Extension Section:** 76.2 mm (3 inches) - **Inside Diameter of Split Barrel:** 34.93 mm (1 ⅜ inches) - **Outside Diameter:** 50.8 mm (2 inches) **Objective:** *Calculate the Area Ratio for the sampler and identify if the sample is disturbed or undisturbed.* **Options:** - **a.** 13.75% (disturbed) - **b.** 111.5% (undisturbed) - **c.** 13.75% (undisturbed) - **d.** 111.5% (disturbed) Understanding the area ratio is crucial for assessing the integrity of the soil sample and analyzing the in-situ conditions of geological materials. This calculation helps inform the choice of sampling methods based on the project's geotechnical requirements.
