Two coaxial shafts \(A\) and \(B\) are geared together through an intermediate parallel shaft \(C\). The wheels connecting \(A\) and \(C\) having a module of \(2 \mathrm{~mm}\) and those connecting \(C\) and \(B\) have a module of \(3.5 \mathrm{~mm}\). Speed of \(B\) is less than \(1 / 10\) th that of \(A\). If the two pinions have each 20 teeth, find suitable number of teeth for the wheels, the actual velocity ratio, and corresponding centre distance of shafts \(C\) and \(A\).
