Neco 2025 Agricultural Science Question 1
Practice objective / multiple choice question 1 from the 2025 Neco Agricultural Science examination.
A lever used in a seed drill is shown in the diagram. The pivot O is fixed. An effort force F is applied at point A, which is \(0.8\) m from the pivot and the line of action makes an angle of \(45^{\circ}\) above the horizontal. The load of \(600\) N acts vertically downward at point B, \(0.25\) m from the pivot. Assuming the lever is in static equilibrium, calculate the minimum magnitude of the effort force F (in newtons) required to hold the load.
