Question: A wheel loader's bucket capacity is rated in cubic metres (cubic yards). Why is it crucial to also consider the material's density (e.g., loose gravel vs. wet clay) when determining a safe load?
Answer options:
- Denser materials cause increased tire wear.
- Denser materials require more fuel to transport. ✅ The weight of the material, not just its volume, affects the loader's stability and operating capacity.
- Density primarily impacts the speed at which material can be loaded.
Correct answer: The weight of the material, not just its volume, affects the loader's stability and operating capacity.
Explanation: While bucket capacity is volumetric, the stability limit of a loader is determined by the weight of the load. Denser materials, even if they don't visually overfill the bucket, can quickly exceed the machine's rated operating weight and compromise stability.
