of Solids Laboratory 2: Build a Beam for 3-Point Bending Abstract: This laboratory report contains the design process of a simple foam I-beam. An analysis of the beam is conducted after the application of a 3-point bending from an ATS machine. This beam experienced a linear stiffness of 262 lbf./in. at an ultimate strength of 53.9 lbf. and deflection of 0.351 in. to which it immediately failed. Objective: This laboratory required the design and construction of a beam that spans 30 inches in order

Results and Description For the first part of the experiment, the results were recorded as a table of deflection measurements from each beam resulting from various loads. This table can be seen in Table 1, in Tables and Figures. The data from this table was then plotted using MATLAB. After plotting, trendlines were drawn to model the data. The graph of the trendlines for each beam, as well as their respective equations can be seen in Figure 1, in Figures and Tables. The best representation

BUILDING 2012 INTRODUCTION The objective of this project is to examine the techniques used in the design of a building. The structural design of this lecture room & office building involves design of floor slabs, stairs, beams, columns, shear walls, foundation and analysis of frames. The building is composed of solid slab, inclined solid slabs & slabs with hole. Live load and dead load analysis is made according to EBCS-1, 1995.After the minimum depth of slab

of Superposition: The normal stress due to pure bending may be combined with the normal stress due to axial loading and shear stress due to shear loading to find the complete state of stress. 4-3 Fig. 4.4 (a) Cantilevered beam with end loading. (b) As portion AC shows, beam is not in pure bending. Copyright © 2015 McGraw-Hill Education. Permission required for reproduction or display.

Problem: Two wooden beams are to support a wooden form filled with concrete as shown. Weight of concrete is 23.5kN/m3. Neglect the weight of the wood. Span of the beam is 5m. Allowable stresses of the wood: bending = 9.72MPa, compression parallel to the grain = 8.6MPa, shear perpendicular to the grain = 2.7MPa, longitudinal shear = 0.85MPa. A. What is the depth of the two beams having a width of 50mm if bending controls? B. What is the depth of the beams having a width of 50mm if shear
