Neco 2025 Physics Question 14
Practice objective / multiple choice question 14 from the 2025 Neco Physics examination.
A motor drives gear A (diameter \(0.20\text{m}\)) at \(1500\text{rpm}\). Gear A meshes with gear B (diameter \(0.40\text{m}\)). Gear B shares its shaft with gear C (diameter \(0.10\text{m}\)), which drives gear D (diameter \(0.30\text{m}\)) attached to a load requiring torque \(12\text{N·m}\). Assuming an overall efficiency of \(90\%\), calculate the minimum torque the motor must supply.
