The question was asked in my homework.

I'm obligated to ask this question of Bearings topic in section Aspects of Design of Mechanical Parts of Design of Electrical Machines

Answer 1

Right answer is (c) 2 or 3

Explanation: The simple thrust bearing cannot pull the radial load and hence guide bearings are used in addition to it. Usually 2-3 guide bearings are used in vertical shaft machines depending upon the load.
