Gce Model Questions Vol1 2024 Agricultural Science Question 15
Practice objective / multiple choice question 15 from the 2024 Gce Model Questions Vol1 Agricultural Science examination.
A tractor of weight 3 t must pull a 5‑t plough across a field that has a 3 % upward grade. The tractor moves at a constant speed of 5 km h⁻¹. Rolling‑resistance coefficient is 0.04, and the soil draft coefficient for the implement is 0.1 kN per tonne of implement weight. The transmission efficiency is 0.85. Using \(g = 9.81\;\text{m s}^{-2}\), calculate the minimum engine power in kilowatts required to maintain the speed.
