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. All calculations are to be done under the assumption that the density of basswood is 28 lbm/ft3 and the modulus of elasticity for basswood is 1.46x106 lbm/in2. Given the constraints of a spending cost of $10.50, a maximum beam weight of 250 grams,

The inclusion of lithium in Reynolds X100 makes sure to block any dislocations within the alloys crystal structure, giving it an outstanding fatigue resistance.

It has an excellent strength to weight ratio obtained from heat-treatment used in its formation. The heat treatment used for this steel does not use quenching rather uses air cooling or air

Introduction During this lab you will become more familiar with the concepts of torque. The purpose of this lab is to determine if the rotational equilibrium condition, Στ = 0, holds experimentally. Equipment Meter stick (1) - no metal ends Fulcrum (1) Clamps (4) Weight Hanger (1) Mass Set (1) Digital Scale (1)

Overall, the 1018 and 1045 steel specimens displayed similar relationships between the heat-treating procedures. The 1045 steel had a greater tensile strength in all states except for the quenched state. In general, the 1018 steel specimens were more ductile than the 1045 steel specimens in all states.

Experiment Two: Stiffness Report from laboratory work performed on 12 May 2011 as a part of the unit of study CIVL2201 Structural Mechanics

Weights acting on the mass hanger were removed to observe more loops that were able to form. Again, the length of the string, tension and number of loops were determined and recorded. The wavelength (w) was calculated

As a result of trail and error method we find the angle for the third pulley and the mass that should had be suspended from it. This will balance the forces deployed on the strings due to the other two masses. While the third force is defined as the equilibrant (������⃗������) Since it is the force that establishes the equilibrium. It is also the negative of the resultant -������⃗������ = ������⃗������ = ������⃗ ������ + ������⃗������. We gathered and recorded the mass and the angle required for the third pulley to enable to put the system into the equilibrium in table 1.

Steel products were defined by several attributes which determined the product application and defined quality. Grade described the metallic (chemical) composition of the steel, or the elements added to the basic recipe of iron and carbon to create the desired properties. Product described the shape of the product, including semi-finished shapes (blooms, billets and bars) and finished shapes (wires and coils). Surface finish described the smoothness and polish that could be applied to the material’s surface to enhance presentation. Size described the latitudinal and longitudinal dimensions of the product. Structural quality described the absence of breaks in the inner metallic structure. Surface quality described the absence of cracks or seams on the surface. Because specific applications called for specific attributes, many products were customized along one or more attributes for the customer. However, of all attributes, customers valued most the grade, which determined product performance.

Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of flexion of the cantilever. Hence, the objective is to establish a relationship between the length of a cantilever, which may give some insight into the physics of cantilevers.

Following tables and graphs show the result of the experiment. The tables will demonstrate the experimental and theoretical deflection for each case. The graphs will show the relationship between the load applied and deflection, in addition to compare the experimental deflection and theoretical deflection.

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.

The tensile test is a standout amongst the most normally utilized tests for assessing materials. The tensile test is done just by grasping inverse finishes of test thing and applying elastic power with the machine. This outcomes in continuous stretching and consequent fracture in the test thing. During this procedure, power expansion information normally are checked and recorded. Malleable test measures properties like extreme rigidity and most extreme stretching specifically simultaneously, utilizing these estimations different properties, for example, Young 's Modulus, Poisson 's proportion and yield quality can likewise be resolved. At the point when appropriately directed, the pliable test results power expansion information that can measure a few vital mechanical properties of a material. The ductile test led for this paper is done in room temperature under the ISO 6892-1 standard.

The deformation and member axial force in Local coordinate system are shown in Figure 4.2.

Dual phase steel has a microstructure which consists of two phases, Ferrite and Martensite (Fig.1). Generally, DP600 steels have a tensile strength of around 600 MPa and total elongation of about 20-25% (Fig2). The tensile strength of DP600 steel can vary from 580-670 MPa.Write uses ???????. Other advantages of DP600 steels are better work-hardening and bake-hardening properties with excellent fatigue strength.
