Which of the following affects the overall weight of the dump truck?

The overall weight of the dump truck is influenced by several factors, all of which contribute to its total mass and how it performs under various conditions.

The type of tires used plays a significant role in the truck's weight. Different tires have varying densities and design specifications, which can add to or reduce the total weight of the vehicle. Heavier-duty tires, for example, can provide better traction and durability, but they also add weight.

The fuel load is another critical factor. As the dump truck carries fuel, this adds to its overall weight. The amount of fuel can fluctuate based on the truck's operational needs, directly affecting how much it weighs at any given time.

Operational equipment inside the truck further contributes to the overall weight. Dump trucks often carry machinery, tools, and other gear necessary for specific tasks. The more operational equipment included, the heavier the truck will be.

Considering all these elements together, it is clear that they collectively affect the total weight of the dump truck, making the correct choice encompass all of the aforementioned factors.
