Beginning with a general presetmodel loading on a beam, a set of four model formulas are established for use in this method.These formulas are expressed in terms of the following: (a) flexural rigidity of the beam; (b) slopes, deflections, shear forces, and bending moments at both ends of the beam; (c) typical applied loads (concentrated force

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

Does it makesense that a mathematical definition of natural frequency exists without knowing if the systemwill oscillate? Can expressions for undamped natural frequency include dissipative terms? Thispaper presents a series of example problems in which these questions arise.Models and BehaviorMass-Spring-Damper Second-Order System Consider the classical lumped-parameter linear model of a mass-spring-damper system,depicted in Figure 1, with mass m, viscous damping b, linear stiffness k, and applied force F(t).
