Neco 2021 Agricultural Science Question 4
Practice objective / multiple choice question 4 from the 2021 Neco Agricultural Science examination.
In the diagram, a tractor engine drives a belt that runs over two pulleys: the driver pulley attached to the engine has a diameter of \(0.5\) m and rotates at \(1500\) rpm. The driven pulley attached to the rotary tiller has a diameter of \(0.2\) m. Assuming no slip, (i) calculate the tiller rotational speed in rpm, and (ii) if the tiller requires a minimum speed of \(3500\) rpm to operate efficiently, decide whether an additional gear reduction is needed and, if so, compute the required gear ratio to achieve at least \(3500\) rpm.
