What is center of gravity and why is it important in EVOC?

• A. The weight of the vehicle's engine only
• B. The point at which weight is concentrated; it affects stability, rollover risk, and steering
• C. The vehicle's top speed capability
• D. The distance between front and rear axles

Answer: (B)

Center of gravity is the balance point of the vehicle’s weight—the spot where all weight can be considered to act. It’s influenced by where heavy components sit and how loads are distributed inside the vehicle. In EVOC, this matters because steering, braking, and acceleration cause weight to shift. A higher or poorly placed center of gravity makes the vehicle more prone to tipping or rolling in turns or during abrupt maneuvers, and it also changes how the tires grab the road, affecting steering feel and stability. Keeping heavy gear low and distributing weight evenly lowers the center of gravity, which improves stability and makes handling more predictable. This concept isn’t about engine weight alone, top speed, or the distance between axles; it’s about where the vehicle’s mass is concentrated and how that location influences stability and control.
