City Guilds Model Questions Vol1 2025 Engineering Question 31
Practice objective / multiple choice question 31 from the 2025 City Guilds Model Questions Vol1 Engineering examination.
A three‑stage gear train is used in a machine. Stage 1 has a driver gear of 20 teeth meshing with a driven gear of 40 teeth. Stage 2 has a driver gear of 30 teeth meshing with a driven gear of 60 teeth. Stage 3 has a driver gear of 25 teeth meshing with a driven gear of 50 teeth. The input torque applied to the first driver is (1500\,\text{N·m}\) and the input speed is (120\,\text{rpm}\). All gear meshes are 95 % efficient except that the total power loss in Stage 2 is known to be (10\,\text{kW}\). Determine the output torque delivered by the final driven gear (in N·m, rounded to the nearest whole number).
