What is the term for the distance between the wheels on the same axis of the truck?

The term that describes the distance between the wheels on the same axis of a truck is known as the "track." This is a crucial measurement as it impacts the stability and handling of the vehicle. A wider track can provide better stability, particularly in a load-bearing scenario, while a narrower track may increase the risk of tipping during sharp turns.

Understanding the track is important when operating heavy machinery or vehicles, as it ensures proper load distribution and can affect the overall safety during operation. The other terms mentioned, such as wheelbase, refer to the distance between the front and rear axles, which is different from the measurement of the track. Center of gravity pertains to the weight distribution of the vehicle, and load center relates specifically to the point where the load is balanced, both of which are important but do not describe the distance between the wheels on a single axle.
