Neco 2019 Physics Question 46
Practice objective / multiple choice question 46 from the 2019 Neco Physics examination.
A block‑and‑tackle system has an ideal mechanical advantage of 4. A load of weight \(400\ \text{N}\) is lifted a vertical distance of \(0.60\ \text{m}\). An operator exerts a constant effort of \(120\ \text{N}\) and pulls the rope through a distance of \(2.50\ \text{m}\).\n\n(a) Determine the actual mechanical advantage and the efficiency of the system.\n\n(b) The same operator wishes to raise the same load through the same \(0.60\ \text{m}\) using a smooth frictionless inclined plane while keeping the effort force at \(120\ \text{N}\). Find the angle of the plane (in degrees, to one decimal place) that will allow this.
