Question 1
A construction project requires moving 50 tons of soil with a rolling resistance of 30 kg per ton. Calculate the total tractive effort needed. Additionally, if the machine has a power rating of 120 horsepower, determine if it can efficiently transport this load while considering general power requirements.
💡 Hint: Consider both the total weight and power metrics relative to the values typical for machinery.
Question 2
Assume a project has different haul route conditions: 100m on hard asphalt with rolling resistance of 45 kg/ton followed by 200m on soft earth with rolling resistance of 80 kg/ton. With a machine weight of 25 tons, calculate the power needed to maintain a consistent speed across the entire distance.
💡 Hint: Break the problem down by each segment to assess power requirements separately.
