Igcse Model Questions Vol1 2019 Physics Question 26
Practice objective / multiple choice question 26 from the 2019 Igcse Model Questions Vol1 Physics examination.
Machine A drives gear A (20 teeth) which meshes with gear B (40 teeth) rotating at \(1500\ \text{rpm}\). The output of gear B drives a belt that turns a pulley of radius \(0.10\ \text{m}\) attached to a load. The belt drive efficiency is 90% and the gear mesh efficiency is 95%. The load requires a power of \(500\ \text{W}\). Calculate the minimum torque that must be supplied by the motor at gear A (in N·m, to 2 s.f.).
