Gce Model Questions Vol1 2021 Agricultural Science Question 15
Practice objective / multiple choice question 15 from the 2021 Gce Model Questions Vol1 Agricultural Science examination.
The diagram shows a tractor of mass 3000 kg pulling a plough. The drawbar is inclined at \(15^{\circ}\) above the horizontal. The plough experiences a soil resistance of 2500 N. The coefficient of rolling resistance of the tractor tyres is 0.02. The tractor moves at a constant speed of 5 km h\(^{-1}\) and the drivetrain efficiency is 85 %. (i) Calculate the total tractive effort that must be developed at the drawbar. (ii) Determine the minimum engine power (in kW) required to maintain this speed.
