Waec Model Questions Vol1 2023 Agricultural Science Question 45
Practice objective / multiple choice question 45 from the 2023 Waec Model Questions Vol1 Agricultural Science examination.
A farmer uses a first‑class lever hoe to break compacted soil. 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 soil resistance) is 0.3 m. The soil offers a resistance of 800 N. (a) Calculate the effort force the farmer must apply. (b) If the farmer can exert at most 250 N, determine the minimum effort‑arm length required (keeping the load arm unchanged) to overcome the soil resistance.
