Statement I: An anti-roll bar reduces body roll.

Statement II: An anti-roll bar softens the ride over a single wheel bump.

In the light of the above statements, choose the correct answer.

  • A.Statement I is incorrect but Statement II is correct
  • B.Statement I is correct but Statement II is incorrect
  • C.Both Statement I and Statement II are correct
  • D.Both Statement I and Statement II are incorrect

Answer: B

The bar does reduce roll, but over a single wheel bump it twists and therefore stiffens that wheel rather than softening it. Its effect on single wheel inputs is the recognised cost of fitting one. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision. The shared behaviour explains why these belong together and the differences explain why both exist.
