Abstract:

In this project we were asked to select an object (L shaped), and apply the outcomes of Solid Mechanics course on it. First of all we have formed a group of five students, and then we have decided to choose a street-light found in one of the university internal streets, so we can apply the required objectives that we are asked for. The project’s main objective was to apply different types of stresses and loads on the street-light. The project was accomplished sequentially by applying each topic that has been taken in the class. The calculations’ procedure will be shown in this project document in details.

Introduction:

All objects in life are subjected to certain type of force(s), in which the weight force is the common one for all objects in life. For our term project, our main force that affects our object is the wind force. Moreover, certain types of loadings are applied to our object. The loadings that the project is concerned about are the following: Centric load, which is a load applied perpendicular to the neutral axis of abeam or column. The load acts through the geometric center (centroid) of gravity. Torsion, which is the twisting or wrenching of a body by the exertion of forces tending to turn one end or part about a longitudinal axis while the other is held fast or turned in the opposite direction; it is the state of being twisted. Eccentric loading, a load on a column or pile which is

    Deflections of a beam are important to be able predict the amount of deflection for a given loading situation. This experiment addresses determining the yield point for a material to fail, so the stress in the material does not have to reach to that point. This is where understanding beam deflection becomes a useful tool. This experiment is using beam deflection theory to evaluate and compare observed deflection per load values to theoretical values. Beam deflection experiment done by four parts. Part 1 -Simple Supported Bean, part 2-Cantilever Beam, part 3-The Principle of Superposition, and Part 4-Maxwell’s Reciprocity Theorem. For part 1 and 2 beam dimensions were recorded and are moment of inertia (I) was calculated using the following formula I=bh3/12.for part1, maximum permissible loads for mid-span and quarter-span were calculated. For part 2 maximum permissible loads for mid-span and end of the cantilever beam were calculated. For both parts different loads were applied and deflections were recorded. After calculating average modulus of elasticity for simple supported beam, which was approximately (-27.6*10^6 psi), it was compared to modulus of elasticity chart. The result indicates that the beam simple supported beam was made of Wrought iron. For cantilever beam, average modulus of elasticity were calculated, which was approximately (9148056.3), and compared with young’s modulus chart .the result indicate that cantilever beam was made of Aluminum. Part 3 reference point was chosen, single concentrated load at other point was applied and deflection was recorded at reference point. Same procedure was applied at another point on the beam and deflection was recorded at reference point. Finally, both loads were applied and deflection was recorded at the…

    An investigation into beam bending and superposition. Being able to analyse how beams bend is an essential tool for all engineers. By using mathematics and material properties, engineers are able to compute structural deformation thus verifying a structures fitness for use. In this experiment a simply supported beam of aluminium is loaded with point forces in three different cases. A clock gauge is positioned in the middle of the beam to measure the deflection. The results of a complex arrangement of forces can be deduced by the superposition of more simple cases. Superposition is possible only when the response of the structure is linear, e.g. when deflection is directly proportional to the applied load. Also the experimental and theoretical deflections of the beam will be compared and a percentage error obtained. There was a second test performed in this investigation demonstrating the influence the 2nd moment of area, also known as the second moment of inertia, had on the load carrying capacity of the beam. The results from test 1 show that it is possible to deduce the deflection of the beam when loaded with point forces by superposition. Results from test 2 show that the deflection of a beam is influenced greatly by its moment of inertia, i.e. with a greater value of inertia there is a smaller deflection.…

    In an effort to compete with film and TV, theatrical stage scenery has been growing larger, more complicated and more ambitions year after year. This trend began with Broadway shows such as Les Misérables and The Phantom of the Opera and continues today. This trend has been expanding from the commercial markets to regional theatres across the country. In order to meet the needs of these large scale and often non-traditional physical productions technical directors and theatre technicians need to understand the forces at work on structural members and be able to determine what is necessary to resist those forces. In the past scenery would often constructed using tried and true methods,…

    Throughout my life I've always had an interest in mechanics. At a young age I was constantly taking things apart to learn how they go together. This mechanical interest has played a huge role in life, dictating my hobbies and interests. My job as a bicycle mechanic is a large interest of mine. It allows me to creatively use my mechanical knowledge to fix problems with bicycles. Outside of work, I recently bought a motorcycle and have since been disassembling and tuning the entire motorcycle to rebuild it. I also take interest in sports such a snowboarding, skateboarding, mountain biking and road biking. Each of these sports have mechanical aspects which appeal to me. Skateboarding has inspired me to build a skatepark in my backyard. Mountain biking has introduced me to trail building, in which you use natural features and wood to create trails that flow through the terrain, typically incorporating jumps that must be built specifically to meet New England Mountain Biking Association standards. I have built my own mountain bike and road bike from the frame up, to the specifications I prefer. My choice in sports and part time job are a reflection of my natural proficiency in mechanical design. I have decided to capitalize on this ability by pursuing an education in mechanical engineering and I believe it will lead me to a deeply fulfilling career.…
