Gce Model Questions Vol1 2017 Physics Question 21
Practice objective / multiple choice question 21 from the 2017 Gce Model Questions Vol1 Physics examination.
A class‑I lever is used to lift a load. The effort of \(120\) N is applied at a distance of \(0.80\) m from the fulcrum, while the load is attached \(0.20\) m on the opposite side. Because of friction at the fulcrum the mechanical efficiency of the lever is \(75\%\). What is the maximum weight of the load (in newtons) that can be lifted?
