Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

How do you convert 20,000 kg into tons?

💡 Hint: Remember the conversion factor: 1000 kg = 1 ton.

Question 2

Easy

If the rolling resistance is 40 kg per ton for 10 tons, what is the total rolling resistance?

💡 Hint: Multiply weight in tons by kg per ton.

Challenge Problems

Push your limits with challenges.

Question 1

A heavy vehicle has a total weight of 40,000 kg. If the rolling resistance is 30 kg per ton and the vehicle must ascend a 6% slope, calculate the total resistance and usable power if the machine can produce 8000 kg of pull.

💡 Hint: Break the problem step by step – first calculate resistances, then find usable power.

Question 2

A road grader weighs 25 tons and experiences rolling resistance of 50 kg per ton. If it must travel on a 4% incline, calculating total resistance and determining if it can tow a 10-ton load given that the available rimpull is 6000 kg.

💡 Hint: Focus on each resistance component methodically for proper answers.
