Neco 2024 Agricultural Science Question 22
Practice objective / multiple choice question 22 from the 2024 Neco Agricultural Science examination.
To lift a 120 kg log, a farmer uses a simple lever. The effort arm (distance from the fulcrum to the point where the farmer applies force) is 1.2 m and the load arm (distance from the fulcrum to the centre of the log) is 0.3 m. Assuming the acceleration due to gravity is \(9.81\ \text{m s}^{-2}\), what is the minimum effort force (in newtons) the farmer must apply to keep the log in static equilibrium?
