Gce Model Questions Vol1 2020 Agricultural Science Question 24
Practice objective / multiple choice question 24 from the 2020 Gce Model Questions Vol1 Agricultural Science examination.
A tractor engine runs at 2400 rpm. The power‑take‑off (PTO) must operate at 540 rpm. The transmission uses two gear stages in series. The first stage can be set to a reduction ratio of either 1.5 : 1, 2 : 1 or 2.5 : 1, and the second stage can be set to 2 : 1, 2.5 : 1 or 3 : 1. Choose a combination of the two stages that gives a PTO speed within ±2 % of the required 540 rpm, and state the resulting PTO speed (to the nearest rpm).
