Neco 2023 Agricultural Science Question 15
Practice objective / multiple choice question 15 from the 2023 Neco Agricultural Science examination.
A tractor pulls a moldboard plough. The draft force required is given by \(D = a + b v^{2}\) where \(a = 1500\) N, \(b = 0.5\) N·s\(^2\) m\(^-2\) and \(v\) is the tractor speed in m s\(^-1\). The tractor moves at 4 km h\(^-1\) and the transmission efficiency is 85 %. Calculate the minimum engine power (kW) the tractor must have to maintain this speed while pulling the plough.
