Challenge Problems
Push your limits with advanced challenges
A construction site requires moving 1000 bank cubic meters of earth. Given that the swell factor is 0.8, and the maximum safe weight of the scraper is 34 tons, calculate how many trips the scraper needs to make assuming each trip can carry a maximum payload of 30 tons.
💡 Hint: Remember to consider both the conversion of volume and weight when calculating trips.
If a haul route has a gradient of 5%, calculate the required resistance in kg per ton and translate this resistance into a total operational cost estimate based on given machinery rates.
💡 Hint: Apply the principles regarding gradients and convert them into the financial aspect of operational costs.
