Practice objective / multiple choice question 9 from the 2024 Neco Model Questions Vol1 Agricultural Science examination.
A hand‑operated seed drill uses a lever that is 0.4 m long from the pivot to the point where the farmer applies effort. The seed hopper (load) exerts a weight of 30 N at a distance of 0.1 m from the pivot.\n\n(a) What is the minimum effort force the farmer must apply to lift the hopper?\n(b) If the farmer makes 0.5 lifting cycles per second, assuming the hopper is raised through a vertical distance equal to its radius (0.1 m) each cycle and neglecting friction, calculate the average power output in watts.
