On the Large Deflections of a Class of Cantilever Beams Moses Frank Oduori‚ Ph.D.‚ Department of Mechanical and Manufacturing Engineering‚ The University of Nairobi. Abstract An equation for the determination of large deflections of beams is derived from first principles. Laboratory tests were carried out in order to validate the theory. The theoretical and experimental results were found to be in good agreement. Introduction In much of the study and practice of mechanical and structural

Cantilever Designed Lab Investigating the relationship between the position of the weight on the cantilever and the amount of deflection Introduction How does the position of the weight on the cantilever affect the amount of deflection? The independent variable of this experiment will be the location of the weight l on the cantilever because it will change throughout the experiment. The dependent variable will be the amount of deflection d because it will depend on the position of the

stiffness of two cantilevered beams composed of steel and aluminum while maintaining both beams at a constant thickness and cross sectional area. The experiment also investigated material properties and dimensions and their relationship to structural stiffness. The experiment was divided into two separate parts. The results for the first part of the experiment were obtained by clamping the beam at one end while applying different masses at a specified length across the beam and then measuring deflection

Bending Moment EXPERIMENT 2B: SHEAR FORCE AND BENDING MOMENT 1. ABSTRACT Performance-based design approach‚ demands a thorough understanding of axial forces. Bending characterizes the behavior of a slender structural element subjected to an external load applied perpendicularly to a longitudinal axis of the element. By this experiment we can verify the limit load for the beam of rectangular cross-section under pure bending. Moments at the specific points are calculated by the method of statics

organisms in our body system react to antibiotics‚ which makes these organisms resistant to antibiotic treatment. Teaching infection control through learning of isolation precaution can decrease the spread of infection in critical care units. The goal of this project is to ensure each person understands the different isolation precautions and practices to minimize the spread of these bacteria to staff‚ visitors and other patients in this unit. Nurses can educate and reinforce protocols to those individuals

deflections of a beam are an engineering concern as they can create an unstable structure if they are large. People don’t want to work in a building in which the floor beams deflect an excessive amount‚ even though it may be in no danger of failing. Consequently‚ limits are often placed upon the allowable deflections of a beam‚ as well as upon the stresses. When loads are applied to a beam their originally straight axes become curved. Displacements from the initial axes are called bending or flexural
