Neco Model Questions Vol1 2019 Agricultural Science Question 29
Practice objective / multiple choice question 29 from the 2019 Neco Model Questions Vol1 Agricultural Science examination.
A hand hoe is used to break a soil patch of \(0.5\) m\(^2\). The soil resistance is \(1500\) N m\(^{-2}\). The hoe blade is \(0.1\) m deep and \(0.2\) m wide. The farmer applies force at the handle, \(0.9\) m from the pivot, while the load acts \(0.3\) m from the pivot. Assuming the tool operates at \(80\%\) mechanical efficiency, determine the average effort force the farmer must apply (in newtons, rounded to the nearest newton).
