The goal of the beam project is to design and construct a beam that can hold a given amount of weight without breaking. The beam is required to hold a concentrated load of 375 lbf on the X-axis and 150 lbf on the Y-axis. The maximum allowable weight of the beam is 250 grams. The maximum allowable deflection for the beam is 0.230 in. and 0.200 in. for the X and Y-axis respectively. The beam is required to be 24 in. in length, and it will be tested on a simply supported configuration spanning 21 in
purpose of this project was to create the best beam design to support a specified load and to discover which type of beam design was the best. The design requirements state that the beam must be made out of basswood, the dimensions must be within a 2”x2” box, the load amount on the X-axis must be 375 lb and Y-Axis must be 150 lb, the weight of the beam must be under 250 g, the cost of the materials for the beam must be under $10.50 and the deflection of the beam must be between 0.06 and 0.25. Twelve designs
Discussion: The beam withstood over 375 lb to the X-axis while deflecting 0.148” which is between the requirements of 0.06” and 0.225”. The beam was under the maximum mass of 250 grams by 75 grams. An I-Beam was chosen because it cost less to manufacture than a hollow box beam and takes less time for the glue to dry since it only has two glue joints. I-Beams have a sturdy design that works well for a simple center point load. The predicted mass was much lower than the actual mass which has due to
A beam or "girder" bridge is the simplest kind of bridge. In the past they may have taken the form of a log across a stream but today they are more familiar to us large box steel girder bridges. There are lots of different types of beam bridges .A Beam Bridge needs to be stiff. It needs to resist twisting and bending under load. In its most basic form, a beam bridge consists of a horizontal beam that is supported at each end by piers. The weight of the beam pushes straight down on the piers. Under
The study of large deflection of cantilever beam comes from theory of elasticity. Theory of elasticity state that “solid material will deform under the application of an external force it will again regain their original position when external force is removed is referred to as elasticity”. We took beam made of nickel titanium alloy which regain their original shape after removing external force act on the beam. It’s a prismatic circular cross section beam. Initial shape and curvature of nickel titanium
Beam launchers work on two phases, beam-placing and moving forwards. The beam-placing operates in two ways depending on where beams are delivered. On one condition, that beams are delivered on the ground level, lifting trolley will pick them up directly by both ends. On the other condition, that beams are delivered at abutment, by two trucks or other carriers at each side, the front trolley will pick up the front end of beams, then the front end of beams will be released from carrier; the front trolley
measured in an attempt to confirm Hooke’s law and the Euler-Bernoulli bending beam theory. In addition, the measured data allows us to calculate the modulus of elasticity (Young’s Modulus) or E of the cantilever beam. Through the course of the experiment our observations revealed that the addition of weights deformed the beam in response to the applied stress. This deformation can be modeled using the Euler-Bernoulli beam bending theory. Our experimentation and calculations revealed that our data did
causing a patient to have malocclusions and misalignments of the jaw. Cone beam computed tomography shows the roots of the teeth with precision while also displaying the bones in the head so that any anomaly can easily be noticed and allow for easier work. There have also been specific studies to determine how each person varies in their nasal passages and how this can cause certain problems in each case. Overall, Cone Beam Computed Tomography proves to be the best option for orthodontists to use
construct and easier to inspect and maintain. Prestressed composite beams have been studied by several authors. In this chapter, a review of the research works carried out on external prestressed composite steel-concrete beam is presented. 2.2 Simply supported plate girders 2.2.1 Behavior and strength Two papers to study the behavior of partially prestressed continuous composite beams consisting of a concrete slab supported by a steel beam were presented by Basu et al. (1987) [7, 8]. In these researches
Solids | | Adam McCreevey | 3/15/2013 | This is a laboratory to learn how to make measurements using a strain gauge by using different configurations, also to determine experimentally the axial and transverse stress at the surface of the beam and compare them to theoretical calculations | Introduction If a length of wire is subject to a stress within its elastic limits, the resulting elongation and change of diameter alters the resistance. The resulting principle is used in the resistance
