1.3. Load Ratio

Try these first

1. 1.

   What is cutting ratio?

   Hint

   It deals with the effectiveness of cutting materials.

2. 2.

   Define load ratio.

   Hint

   It reflects the blade's ability to push materials.

3. 3.

   What does a high cutting ratio indicate?

   • Less power concentration
   • Greater ability to cut hard materials
   • Lower efficiency

   Hint

   Think about what cutting efficiency means.

4. 4.

   True or False: Load ratio is irrelevant when assessing blade performance.

   • True
   • False

   Hint

   Consider the importance of pushing power.

5. 5.

   If a bulldozer has a horsepower of 200 and a cutting edge length of 5 meters, calculate the cutting ratio.

   Hint

   Use the formula provided earlier.

6. 6.

   In a practical scenario, if a U blade struggles to push through dense clay while a straight blade performs better, discuss why that might be.

   Hint

   Reflect on the effects of blade design.
