Correct answer is (a) Elemental area with uniform cross section

Explanation: Modeling is one of the basic steps in finite element method. Let us model a stepped shaft consists of discrete no of elements each having a uniform cross sectional area. Average cross section area within each region is evaluated and used to define elemental area with uniform cross sectional area.

 A1=A1’+A2’/2.
