Practice objective / multiple choice question 41 from the 2020 City Guilds Model Questions Vol1 Engineering examination.
A motor runs at \(1500\) rpm and delivers a torque of \(0.5\) Nm. It drives a gear train as follows: gear \(A\) (20 teeth) meshes with gear \(B\) (40 teeth). Gear \(B\) is fixed on the same shaft as gear \(C\) (30 teeth), which in turn drives gear \(D\) (60 teeth). Each mesh operates at \(90\%\) efficiency. Determine (i) the rotational speed of gear \(D\) in rpm, and (ii) the torque transmitted by gear \(D\) (to two decimal places).
