1.1. Conversion of Vehicle Weight

Try these first

1. 1.

   If a vehicle weighs 30,000 kg, how many tons does it weigh?

   Hint

   Remember, 1000 kg equals 1 ton.

2. 2.

   What is the rolling resistance for a vehicle with a gross weight of 25 tons and resistance value of 10 kg per ton?

   Hint

   Use the formula: Gross weight × Rolling resistance value.

3. 3.

   What is the conversion rate of kg to tons?

   • 1 ton = 500 kg
   • 1 ton = 1000 kg
   • 1 ton = 2000 kg

   Hint

   Think about how many kilograms are in one ton.

4. 4.

   Grade resistance increases with an increase in slope percentage. True or False?

   • True
   • False

   Hint

   Consider what happens when you climb a hill.

5. 5.

   A tractor weighing 55 tons must navigate a haul road with a rolling resistance of 45 kg/ton and a grade of 7%. Calculate the total resistance they face.

   Hint

   Break down the problem into calculation of each resistance first.

6. 6.

   If a vehicle has a rolling resistance of 80 kg/ton at 60 tons and experiences a 4% slope, what will its total resistance be?

   Hint

   Calculate rolling resistance first, then the grade resistance.
