Marker's Feedback
2018/DEC >> Parts (a) and (b) Most candidates had no problems here.
>> Part (c) A lot of candidates just said damage to stator, damage to rotor, damage to crankshaft etc. The question asked for types of damage and should have been along the lines of deformation, crack propagation and twisting etc.
