Question

In oscillation of sprung weight, ............... occurs by turning or driving the vehicle on a bumpy road, in which the springs on one side of the vehicle expand, while those on other side contract.

• A. rolling
• B. pitching
• C. bouncing
• D. yawing

Hint:

Tip: Cornering or side tilt = rolling. Forward-back = pitching. Up-down = bouncing. Rotation = yawing!

Answer 1

The Correct Option is A

Vehicle body movements can be described using different motions: rolling, pitching, bouncing, and yawing.
Rolling occurs when the vehicle tilts sideways, typically while cornering or driving over uneven surfaces.
This happens because the springs on one side compress while the springs on the other side expand.
Rolling affects vehicle stability and comfort, and is an important factor in suspension design.
Pitching is the front-to-back tilting motion, bouncing is vertical up and down, and yawing is rotation around the vertical axis.
Given the description of side-to-side spring expansion and contraction, the correct answer is rolling.
