What effect can a surging liquid load have on how a tanker handles?
Correct answer: It can shove the truck the same way the waves are moving.
Answer options
- AIt lets the truck get around corners more tightly
- BIt adds to the wind drag working against the truck
- CIt can shove the truck the same way the waves are moving Correct
Why
In a partly filled tank, a heavy mass of liquid can slosh around, and its momentum pushes on the vehicle. A wave rolling forward as you brake can push the truck ahead and lengthen your stop, while a wave rolling sideways in a turn can help tip it over.
