(a) Elimination approach

(b) Multiple constraints

(c) Penalty approach

(d) Minimum potential energy theorem

The question was asked in class test.

I would like to ask this question from Finite Element Equations topic in chapter One Dimensional Problems of Finite Element Method

Answer 1

Correct choice is (b) Multiple constraints

To explain: Multiple constraints is one of the method for boundary conditions it is generally used in problems for modeling inclined rollers or rigid connections.
