Question

Difficulty: EasyBalance and Center of Gravity

Distributing cargo so that the heaviest items are placed on top of lighter freight lowers the vehicle's center of gravity and decreases the likelihood of a rollover.

Answer: Answer

Answer

False. Placing heavy cargo on top of lighter freight raises the center of gravity, significantly increasing the danger of a rollover.
The statement is false because safe cargo distribution requires placing the heaviest items at the bottom of the load. Loading heavy cargo on top of lighter items raises the center of gravity, making the vehicle top-heavy and dramatically increasing the risk of rolling over when navigating curves or executing sudden steering maneuvers.

Step-by-Step Solution

1
Analyze standard cargo loading principles regarding center of gravity and vehicle balance.
To maintain maximum vehicle stability, cargo must be distributed as low as possible, placing the heaviest parts underneath lighter freight.
Keeping mass close to the road surface establishes a low center of gravity.
2
Evaluate the effect of stacking heavy items on top of lighter freight.
Stacking heavy freight high raises the overall center of gravity, creating a top-heavy load condition.
A high center of gravity increases centrifugal tipping forces on curves and during lane changes.
3
Determine the truth value of the presented statement.
The statement is False.
The statement incorrectly claims that placing heavy freight on top lowers the center of gravity and reduces rollover risk.
