Answer» The CORRECT option is (a) Cast steel Easy explanation: The crankshaft was initially forged but LATER on casting of the crankshaft has ALSO become quite common. The cast crankshaft both steel as WELL as S.G iron have been used. The S.G iron has a high strength cast iron in which carbon is in the form of spherical modules of GRAPHITE.
