is based onfinding the root between two points, the method falls under the category of bracketing methods.Given a closed interval [a, b] on which f (x) changes sign, we divide the interval in half and notethat f must change sign on either the right or the left half (or be zero at the midpoint of [a, b].)We then replace [a, b] by the half-interval on which f changes sign. This process is repeated untilthe interval has total length less than . In the end we have a closed interval of length less thanon which f changes sign. The Intermediate Value Theorem (IVT) guarantees that there is a zeroof f in this interval. The endpoints of this interval, which are known, must be within of thiszero.The method is based on the following

This method can be applied to solve most problems involving beam reactions anddeflections encountered in the teaching and learning of mechanics of materials. On the otherhand, the conjugate beam method is a natural extension of the moment-area theorems. It is anelegant, efficient, and powerful method propounded by Westergaard in 1921. Elementarypresentation of this method did appear in some early textbooks of mechanics of materials.2,5 Forreasons unknown, this method is currently missing in most such textbooks.This paper is aimed at providing comparisons of the method of model formulas versus theconjugate beam method regarding their (a) pedagogy and methodology, (b) effectiveness insolving

A numberof issues appear in the area of student learning on Mohr’s circle, namely, (a) Identification of the relationship of the load on a member and the state of stress at a point.
