Neco Model Questions Vol1 2020 Agricultural Science Question 45
Practice objective / multiple choice question 45 from the 2020 Neco Model Questions Vol1 Agricultural Science examination.
A farmer uses a hand‑operated lever to lift a \(120\ \text{kg}\) sack of grain onto a platform. The lever is a rigid rod \(1.2\ \text{m}\) long and is pivoted \(0.3\ \text{m}\) from the load end (distance from load to fulcrum). The effort is applied at the opposite end, making an angle of \(30^{\circ}\) with the rod. Assuming the lever is frictionless, calculate the magnitude of the effort force required (in newtons). Use \(g=9.81\ \text{m s}^{-2}\).
