Question 15
The set of four rollers shown has fixed axles and transfers rotation from each roller to the next without slipping. Their diameters are 21 cm, 32 cm, 50 cm and 14 cm respectively.
While the 21 cm roller makes a full rotation $(360^\circ)$, through which angle does the 14 cm roller rotate?
