Gce Model Questions Vol1 2019 Agricultural Science Question 38
Practice objective / multiple choice question 38 from the 2019 Gce Model Questions Vol1 Agricultural Science examination.
A rotary tiller requires a draw‑bar pull of \(12\) kN while moving forward at \(5\) km h⁻¹. The tractor that will pull it has a transmission efficiency of 85 % and tyre rolling‑resistance coefficient of 0.03.\n\n(a) Calculate the minimum engine power (in kW) the tractor must develop.\n(b) If the tractor runs at 2000 rpm and the final‑drive ratio is 6:1, determine the required engine torque (in N·m). Round the power up to the nearest whole kilowatt and the torque to the nearest newton‑metre.
