4.3. Economics of Rounding Truck Numbers

Try these first

1. 1.

   What is gravimetric capacity?

   Hint

   Consider what happens if this limit is exceeded.

2. 2.

   Define loading time.

   Hint

   Think about the factors that contribute to this time.

3. 3.

   What is the gravimetric capacity of a truck?

   • The maximum weight it can carry
   • The volume it can hold
   • The speed of operation

   Hint

   Think about the definition provided earlier.

4. 4.

   True or False: Overloading a truck can lead to increased operating costs.

   • True
   • False

   Hint

   Reflect on the implications discussed.

5. 5.

   You have a truck with a gravimetric capacity of 24,000 pounds and you're using a material with a density of 1.5 pounds per cubic foot. Calculate the maximum volume that can safely be loaded.

   Hint

   Remember to apply the density formula correctly.

6. 6.

   If your excavator can fill a bucket every 1.2 minutes and you need to load 8 buckets to fill a truck. Calculate the total loading time required.

   Hint

   Use the cycle time and the number of buckets to find the solution.
