Neco Model Questions Vol1 2024 Agricultural Science Question 42
Practice objective / multiple choice question 42 from the 2024 Neco Model Questions Vol1 Agricultural Science examination.
A block‑and‑tackle system is set up as follows (see the diagram). Two fixed pulleys (P1 and P2) and one movable pulley (P3) are used. The load of \(600\) N hangs from the movable pulley. The rope passes over P1, under P3, over P2, and the free end is pulled vertically as the effort. Each pulley causes a 10 % loss of tension; that is, the tension on the outgoing side of a pulley equals \(0.9\) times the tension on the incoming side.\n\nCalculate the magnitude of the effort force the farmer must apply to lift the load.
