Waec Model Questions Vol1 2017 Agricultural Science Question 43
Practice objective / multiple choice question 43 from the 2017 Waec Model Questions Vol1 Agricultural Science examination.
A farmer needs to lift a 200 kg sack of fertilizer onto a platform 1.2 m high using a simple lever. The lever is 2.5 m long and the fulcrum is placed 0.5 m from the load end. Assuming the farmer applies a vertical effort at the opposite end and neglecting friction, (a) calculate the minimum effort force required, and (b) if the farmer can exert at most 400 N, determine whether this arrangement is adequate; if not, find the greatest permissible distance from the fulcrum to the load end that would allow lifting with a 400 N effort.
