Which statement about the baffles in a liquid cargo tank is true?

Correct answer: They do little to reduce side-to-side surge.

Answer options

  1. AThey do little to reduce side-to-side surge Correct
  2. BThey do little to reduce front-to-back surge
  3. CThey prevent surge in every direction

Why

Baffles break up the forward and backward rush of the liquid, which is why baffled tanks have weaker front-to-back surge. They are not built to block movement from side to side, so that surge can still build up, especially in turns, and can roll the vehicle over.
