Question

What should be the first property of the shaft design?

(a) the shaft design should be such that the shaft must have enough corrosion resistance

(b) the shaft design should be such that the shaft must have enough mechanical strength

(c) the shaft design should be such that the shaft has enough tensile strength

(d) the shaft design should be able to withstand the voltage fluctuations

The question was posed to me in an interview for internship.

Asked question is from Design of Shaft in portion Aspects of Design of Mechanical Parts of Design of Electrical Machines

Answer 1

Correct option is (b) the shaft design should be such that the shaft must have enough mechanical strength

The best I can explain: The shaft design should be such that the shaft must have enough mechanical strength. The strength should be such that it should withstand all loads without causing much residual strain.
