Question

Difficulty: MediumSpecial Cargo: Livestock and Hanging Meat

A commercial trailer transporting hanging meat has a higher center of gravity and a greater risk of rolling over on curves compared to a trailer carrying an equal weight of cargo secured flat on the floor.

Answer: Answer

Answer

True
The statement is true because overhead track suspension shifts the load's center of mass upward toward the trailer roof and introduces lateral pendulum motion during turns, significantly heightening rollover danger.

Step-by-Step Solution

1
Analyze the vertical mass distribution of suspended cargo versus floor-mounted cargo.
Hanging meat is suspended from overhead ceiling tracks, elevating the center of mass, whereas floor-loaded cargo keeps the weight close to the axles.
Vehicle rollover stability is directly determined by the height of the center of gravity relative to the wheel track width.
2
Evaluate the dynamic forces acting on the vehicle during turning maneuvers.
The elevated center of gravity and pendulum motion of swinging carcasses generate severe lateral rollover forces even at speeds below posted limits.
Higher center of mass and dynamic cargo sway dramatically reduce the lateral acceleration needed to cause a rollover.
