1.	What happens in the case of the small shafts?(a) the diameter in the bearings should be about 1/3 of the maximum diameter(b) the diameter in the bearing should be about 2/3 of the maximum diameter(c) the diameter in the bearing should be about 2/5 of the maximum diameter(d) the diameter in the bearing should be about 1/5 of the maximum diameterI have been asked this question by my college director while I was bunking the class.I'd like to ask this question from Design of Shaft in section Aspects of Design of Mechanical Parts of Design of Electrical Machines
Answer» Right option is (B) the diameter in the BEARING should be about 2/3 of the MAXIMUM diameter The EXPLANATION: The diameter of the shaft in the bearings is less than the diameter under the armature. The diameter in the bearing should be 2/3 of the maximum diameter.
