Dry bulk tanks:
Answers
Usually have a low center of gravity.
Usually have a high center of gravity.
Are usually not allowed to cross railroad tracks.
The Correct Answer and Explanation is :
The correct answer is: Usually have a high center of gravity.
Explanation:
Dry bulk tanks are specialized trailers used to transport bulk dry materials like grains, powders, chemicals, and cement. These materials are typically stored in large, cylindrical tanks, and because of their design and the type of cargo they carry, these tanks usually have a high center of gravity.
Why do dry bulk tanks have a high center of gravity?
The center of gravity in any vehicle refers to the point where its weight is evenly distributed. For dry bulk tanks, the center of gravity is higher compared to other types of vehicles like flatbeds or liquid tankers. This is due to several factors:
- Shape of the tank: Dry bulk tanks are often cylindrical, and when the material is loaded into these tanks, the distribution of weight tends to sit higher within the tank.
- Type of cargo: Unlike liquid cargo, which can settle at the bottom of a tank, dry bulk materials can shift more easily within the tank. As a result, the weight distribution tends to be less stable, further raising the center of gravity.
- Empty space: The nature of dry bulk transportation means that the tanks may often carry varying amounts of cargo, and when the tank is not full, the load can shift and create an even higher center of gravity.
Risks Associated with a High Center of Gravity:
A high center of gravity makes the vehicle more prone to tipping over, especially in sharp turns or during sudden maneuvers. For example, when making a turn at higher speeds, the high center of gravity can cause the tank to become unstable, leading to potential rollover accidents. This is why drivers of dry bulk tanks must be cautious of their speed and handling.
In contrast to the other options, dry bulk tanks are usually allowed to cross railroad tracks and their design prioritizes cargo capacity over maintaining a lower center of gravity.
