Neco 2025 Agricultural Science Question 18
Practice objective / multiple choice question 18 from the 2025 Neco Agricultural Science examination.
A farmer uses a two‑stage lever to lift a \(200\) kg sack of grain. The first lever is a class‑2 lever with an effort arm of \(0.8\) m and a load arm of \(0.2\) m. The output force from the first lever is applied to the effort arm of a second class‑1 lever whose effort arm is \(0.5\) m and load arm is \(0.25\) m. Assuming no losses, what is the minimum effort force the farmer must apply at the end of the first lever to lift the sack? Give your answer in newtons (use \(g = 9.8\) m/s²).
