Practice objective / multiple choice question 19 from the 2017 Neco Agricultural Science examination.
Refer to the diagram of a hand‑hoe lever system. The pivot O is located 0.30 m from the blade where the soil resistance of 150 N acts perpendicular to the blade. The farmer applies a force at the handle point H, which is 1.20 m from the pivot and makes an angle of 30° with the horizontal. Assuming the system is in static equilibrium, determine the magnitude of the force the farmer must exert at H (in newtons).
