Neco 2021 Agricultural Science Question 34
Practice objective / multiple choice question 34 from the 2021 Neco Agricultural Science examination.
A farmer uses a compound lever system to lift a 200 kg sack of grain. The first lever is a class 1 lever with an effort arm of 0.8 m and a load arm of 0.2 m. Attached to the load arm is a class 2 lever whose effort arm is 0.5 m and load arm (distance from its fulcrum to the sack) is 0.1 m. Assuming ideal (frictionless) levers, what minimum effort force (in newtons) must be applied to the first lever to lift the sack? (Use \(g=9.8\) m s⁻².)
