Lab #03 Studying Beam Flexion Summary: Beams are fundamental structural elements used in a variety of engineering applications and have been studied for centuries. Beams can be assembled to create large structures that carry heavy loads, such as motor vehicle traffic. Beams are also used in micro- or nano-scale accelerometers to delicately measure and detect motions that trigger the deployment of an airbag. From a technical standpoint, a beam is a structure that supports transverse load. Transverse load is load that is perpendicular to the long axis of the beam. As a result, of transverse load, beams undergo bending, in which the beam develops a curvature. As the beam bends, material fibers along the beam’s long axis are forced to stretch or contract, which in turn causes a resistance to the bending. The fibers that are the farthest away from the center of the beam are forced to stretch or contract the most and thus, material at these extremities is the most important to resist bending and deflection. This topic is studied quantitatively in Strength of Materials (CE-303). Purpose: The purpose of this assignment is to accomplish the following goals: • Develop a simple experiment to achieve a goal. • Statistically and observationally analyze your data and interpret the results. • Summarize and present your data, results and interpretations. Procedure: 1. Working as a team, develop a procedure to carefully document the amount of bending a beam under-goes as loads are placed on it (this is your experimental protocol). You must select at least two different beam styles. 2. Collect the data points your experimental protocol calls for. You should conduct at least three trials and the order of data collection within those trials should be randomized. 3. Using the provided Excel deflection calculator, calculate the “predicted” deflection for each of the trials in your protocol. 4. Please observe the following MAXIMUM test torques to avoid damaging the beams. • Width Effect Beams: Small beam: 48 in-lbs, Medium beam: 80 in-lbs, Large beam: 120 in-lbs • Depth Effect Beams: Small beam: 8 in-lbs, Medium beam: 48 in-lbs, Large beam: 160 in-lbs Report and Presentation Requirements: 1. Title Page: Should include the title of the lab experiment, groups individual names (in alphabetical order by last name), data collection date, report due date, and course name and section. 2. Introduction: Briefly explain what you are trying to accomplish with this experiment. 3. Hypothesis Development: Should clearly state the three hypotheses, with respect to distance, beam size, and calculated versus actual deflection. Be sure to include logic to support your educated guess. 4. Method: Explain each activity performed during the data collection and analysis process. Provide a list of the equipment used and its purpose. 5. Analysis and Results: (1) Using the raw data, provide a table of descriptive statistics (mean, variance, and range) for each beam at each distance. (2) Provide a data table (average across 3 trials) showing the deflection for each beam at each distance. (3) Create one or more charts demonstrating the difference, if any, between the calculated and observed deflection for each beam. (4) Use the t-Test: Paired Two Sample for Means in Excel to determine if there is a statistically significant difference between predicted (calculated) deflection and actual (observed) deflection, assuming α = 0.05. Show the results for each beam. Note: To add in the Data Analysis package (under the data tab), go to Office Button -> Excel Options -> Add-Ins -> Manage Excel Add-Ins -> GO… -> check Analysis TookPak and click OK. For each table or chart, provide a description and explanation of what is being displayed. 6. Conclusions: Restate the hypotheses and explain whether or not the educated guess was correct. Include limitations of the experiment (in other words, describe other factors that would make the experiment better or possible errors associated with the experiment). Provide suggestions for future research. 7. Last Page: Include, at the end of the document, a summary of all the tasks required to complete the assignment, and which member or members of the group were principally responsible for completing those tasks. This should be in the form of a simple list. 8. Presentation: Summarize the report, excluding the last page. Due Date: This assignment is to be completed and turned in at the beginning of your laboratory meeting during the week of 11th March.
