Question

What is the second property of the shaft design?

(a) the shaft design should be such that it has high rigidity

(b) the shaft design should be such that it should have high tensile strength

(c) the shaft design should be such that it should have high corrosion resistance

(d) the shaft design should be such that it should withstand voltage fluctuations

The question was asked in my homework.

I would like to ask this question from Design of Shaft topic in portion Aspects of Design of Mechanical Parts of Design of Electrical Machines

Answer 1

Correct choice is (a) the shaft design should be such that it has high rigidity

To elaborate: The second property of the shaft design such that it should have high rigidity. The rigidity should be such that the deflection of shaft under operation of machine does not reach such a dangerous value as to cause the rotor to touch the stator.
