Beam Project

After the analysis on the first design brought to light the zero for members, it was decided that these members should be removed. In order to combat the flex of such a simple design the decision was made to double the thickness. This design would have the same outer frame of two triangles with a height of 20 centimeters and a width of 40 centimeters. Instead of being spaced five centimeters apart the wood be bonded directly together using Gorilla Glue. Balsa wood, a very lightweight wood with properties similar to a dense foam, was used for the main supporting member. Basswood, a lightweight yet firm wood, was used for the horizontal member. The final design added a triple layer sheet of balsa wood to rear side of the truss. This balsa sheet was added for the purpose of mounting and supporting the main structure. Additionally, a five centimeter square frame of bass wood was added at the end of the boomilever to place the loading block for testing. Once this design was implemented two key issues were discovered. First, due to the properties of the bass wood and balsa wood it was obvious that the placement needed to be reversed. The bass wood should be used for the hypotenuse and the balsa wood should be used for the

Michael Yoo used several definitions from several different places to define torture in his argument. The first definition is the one he used when he defined torture as the following: act committed by a person acting under the color of law specifically intended to inflict severe physical or mental pain or suffering (other than pain or suffering incidental to lawful sanctions) upon another person within his custody or physical control. The other definition he uses it used to show what the government defines torture as. This definition is as follows: The United States

b) Determine the distance, x, from the left end of the beam to the point where the rope is attached. Note: take the torque about the left end of the beam.

Adding additional uplift capacity to the stringers while minimizing changes to the beam cross section will be essential to preventing future damage to the stringers

that each seat in the restaurant will require about 7 barrels of beer (best case scenario) per year.

I received the last assignment dropbox comments. Forgive me with disappointing you with the overall quality of my last assignment. However, I have been researching and working nonstop to correct my weakness in this skill.

One thing that has been brought up as a concern for the hospital is using unistrut versus structural steel to hold booms from the ceiling. Unistrut tends to move too much and causes too much movement in the booms when doctors are in surgery. The engineer on the project has started to investigate this problem and has agreed to use structural steel instead of unistrut. In my Structural Systems I class, we learned how structural steel deflects with certain

This report has been written to describe an experiment performed on a channel section examining the stiffness of the beam through two differing types of deformation – curvature and deflection. The aim of the experiment was to determine the value of the flexural rigidity (EI) in two different ways; using the curvature, k, and the mid-span deflection. The testing method used for the experiment is described. The experiment found that the EI values calculated were as follows: - EIcurv = 1.76E+10 Mpa.mm4 when calculated using the curvature, k. - EIdefl

We are using nitinol (nickel titanium alloy) beam it’s having a low modulus of elasticity (E) which shows good spring back behavior which regain its original shape after removing external load. Who’s bending stiffness is low compared to other material like stainless steel. Due to this property at very low external load large deflection take place in the beam. We are going to find the deflection in

Officially launched a year ago, the AMP project, acronym for Accelerated Mobile Pages, is undoubtedly one of Google's priority projects. After a presentation to the general public, Google announced the official release of its AMP (Accelerated Mobile Page) project. It is indeed Google as the leader and its lobbying around AMP is at least active.

Below are two tables in which I have recorded the data which I obtained during the experiment. The first table reflects the Relationship between the deflection/flexion of the cantilever and the mass of the load and the second table reflects the relationship between the flexion of the cantilever and the length of the cantilever.

The beam was loaded the mid-length in 2.745 lbs. increments up to 6.745 lbs. The change in clearance of every load step was measured and data was recorded.

Table 1 & 2: First, find the mass of the wooden block and record the data. Then place the wooden block on the inclined plane (at 0o) with the wide side down. The height of the pulley should be the same height as the screw location on the wooden block. Then hang a weight on the opposite side of the hanger and add weights until block starts to move with a constant velocity (push block to overcome fs¬). Then record the resulted weight of the hanger in Table 1 (as F). Add 500 g to the wooden block and repeat the process. Replace 500 g with 1 kg on the wooden block. Repeat the process described above.

Based on this theory, Ahlbeck et al. initiated their model (Lumped mass model) which represents only the vertical effect of the sleeper and the ballast as shown in Figure 2.1.2. This model cannot be used in high-frequency vibration[5]. Also, Ahlbeck et al. (as cited in Sun & Dhanasekar 2002)[4] find formulas for determining the stiffness value Kbl as well as the mass of the Trapezoidal part of the rail ballast under a sleeper Mbl as:
