Question

The vector q=[q1,q2………q8]^T of a four noded quadrilateral denotes ____

(a) Load vector

(b) Transition matrix

(c) Element displacement vector

(d) Constant matrix

I had been asked this question by my college professor while I was bunking the class.

My question comes from Two Dimensional Isoparametric Elements topic in chapter Two Dimensional Isoparametric Elements and Numerical Integration of Finite Element Method

Answer 1

Right choice is (c) Element displacement vector

Explanation: A displacement is a vector whose length is the shortest distance from the initial to the final position of a point P. It quantifies both the distance and direction of an imaginary motion along a straight line from the initial position to the final position of the point.
