Gce Model Questions Vol1 2020 Agricultural Science Question 39
Practice objective / multiple choice question 39 from the 2020 Gce Model Questions Vol1 Agricultural Science examination.
A 75\,kW tractor supplies power to a rotary tiller through the PTO, which runs at a maximum of 540\,rpm. The tiller operates most efficiently at 1\,200\,rpm and must not receive more than 400\,Nm of torque. The transmission can be set with two gear stages, each having an integer ratio between 1\!:\!1 and 5\!:\!1 (input\!:\!output). Find a pair of gear ratios (stage 1 and stage 2) that will give the required tiller speed while keeping the torque below the 400\,Nm limit. If no such combination exists, state that it is not feasible.
