Waec Model Questions Vol1 2018 Agricultural Science Question 10
Practice objective / multiple choice question 10 from the 2018 Waec Model Questions Vol1 Agricultural Science examination.
The diagram shows a tractor equipped with a power take‑off (PTO) shaft that drives a rotary tiller. The PTO delivers a torque of 250 Nm at 540 rpm. A gear set reduces the speed to half (ratio 1:2) before it reaches the tiller. The belt drive between the gear set and the tiller has an efficiency of 90 %. The tiller requires a minimum torque of 200 Nm to overcome soil resistance. Using the information in the diagram, determine whether the tractor can operate the tiller and state the maximum torque available at the tiller shaft (in Nm).
