Gce Model Questions Vol1 2020 Agricultural Science Question 21
Practice objective / multiple choice question 21 from the 2020 Gce Model Questions Vol1 Agricultural Science examination.
A tractor is to pull a plough that requires a draft force of 12 kN on level ground. When moving up a 5 % slope, the required force increases by 10 % due to the grade. The tractor's drivetrain efficiency is 80 %. It will travel at a constant speed of \(5\ \text{km h}^{-1}\). Calculate the minimum engine power in kilowatts (kW) that must be developed to maintain this speed up the slope.
