Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the rolling resistance for a machine weighing 30 tons with a resistance of 20 kg/ton?
💡 Hint: Calculate by multiplying the weight in tons by the resistance value.
Question 2
Easy
If a machine sinks 5 cm into the surface with a resistance of 4 kg/ton, what is the penetration resistance for 10 tons?
💡 Hint: Use the formula: Penetration Resistance = Depth in cm * Resistance kg/ton * Weight in tons.
