Question

Difficulty: EasyBalance and Center of Gravity

Placing excessive weight directly over the steering axle of a commercial motor vehicle makes the steering wheel feel overly light and reduces front tire traction.

Answer: Answer

Answer

False
The statement is false because concentrating too much weight over the steering axle increases tire resistance against the pavement, making the vehicle hard to steer and putting excessive stress on the steering axle. In contrast, placing weight too far toward the rear lightens the front axle and degrades steering control.

Step-by-Step Solution

1
Analyze how placing excessive cargo weight over the front steering axle affects vehicle steering mechanics.
Excessive front-axle weight increases the downward friction load on the front tires and adds stress to the steering linkage.
Cargo weight placement directly determines axle loads, tire road contact force, and the physical effort required to steer.
2
Evaluate whether front overloading produces light steering and traction loss.
The statement's claim is false; front overloading causes heavy, hard steering, whereas rear overloading causes light steering and traction loss.
Underloading the steering axle causes light steering and traction loss, not overloading it.
