A continuously variable transmission controls output speed by

  • A.switching between a fixed set of gear ratios in sequence
  • B.changing the effective diameters of its driving elements
  • C.slipping a fluid coupling between the input and the output
  • D.inducing currents in a conducting drum between two shafts

Answer: B

Correct answer: changing the effective diameters of its driving elements

A continuously variable transmission runs a belt or chain between conical pulleys whose flanges move axially, so the radius at which the belt rides - and therefore the ratio - changes smoothly without steps. It is a mechanical ratio change with no slip in the power path, so it is efficient across its range.
