Neco 2017 Physics Question 31
Practice objective / multiple choice question 31 from the 2017 Neco Physics examination.
A lever is used to lift a load of \(120\ \text{N}\). The load is attached \(0.20\ \text{m}\) from the fulcrum. The effort is applied on the opposite side of the fulcrum. Due to friction at the pivot, a resisting torque of \(5\ \text{N·m}\) acts opposite to the motion. If the maximum permissible effort force is \(40\ \text{N}\), what is the minimum distance from the fulcrum at which the effort must be applied to lift the load? Give your answer in metres to two decimal places.
