Question

In elimination approach method, extract the displacement vector q from the Q vector. By using ___

(a) Potential energy

(b) Load

(c) Force

(d) Element connectivity

I got this question during an online interview.

This intriguing question comes from Finite Element Equations in portion One Dimensional Problems of Finite Element Method

Answer 1

The correct answer is (d) Element connectivity

Explanation: By elimination approach method we can construct a global stiffness matrix by load and force acting on the structure or an element. Then we extract the displacement vector q from the Q vector. By using Element connectivity, and determine the element stresses.
