That these facets of the course were immediately obvious toobservers who were unaware of the course aims is very encouraging. Other observationsin their report for included: a) considerably higher attention paid by the students in the experimental course (no sleeping, considerably less cell phone checking), b) students in the traditional lecture were very passive (taking notes from the board) while students in the experimental course were actively engaged (working on problems, discussing their designs with other groups, presenting

impact. It follows from analysis, therefore, that increasing the dropheight increases the energy that is dissipated during impact [15,24].Similarly, from the relation between linear impulse and linear momentum, the vertical impulsethat acts on the particle during impact is given by [1-6] ∫ ⃗ (⃗⃗⃗⃗ ⃗⃗⃗⃗⃗)where the subscript “a” stands for ‘after impact’ and “b” stands for ‘before impact’. Hence, ta isthe time immediately after impact and tb is that immediately before impact. Similarly, Va is thespeed immediately after impact and Vb is that immediately before impact. Since energy isconserved during the free fall of the ball before the impact occurs and is conserved again duringrebound of the ball after

needed in using the model formulas inthis method. 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

In this paper the transformation of stresses is not specificallyaddressed, but the principal stresses and the associated principal directions are obtained for thefour biaxial stress situations identified above. Mohr’s circle is one of the most difficult topics in Mechanics of Materials course. 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. (b) Confusion between the stress axes and the spatial coordinate axes (c) Inability to perceive rotation of the principal axes. (d) Relevance of Mohr’s circle without reference to yield and fracture criteria. (e
