Neco Model Questions Vol1 2024 Agricultural Science Question 49
Practice objective / multiple choice question 49 from the 2024 Neco Model Questions Vol1 Agricultural Science examination.
A farmer uses a first‑class lever to lift a sack of grain weighing \(150\) kg. The distance from the fulcrum to the sack (resistance arm) is \(0.4\) m, while the distance from the fulcrum to the effort point is \(1.2\) m. Because of friction at the pivot, the mechanical advantage is reduced by 10 %. Taking \(g = 9.8\;\text{m s}^{-2}\), determine the minimum effort force (in newtons) that must be applied to lift the sack.
