Executive Summary:
Tensile tests are carried out to enable us understand the properties of different materials and how they behave when under load. In the lab we tested two kinds of metal. Two aluminum (Ax and Ay) and three steel (Sx, Sy, and Sz). We used two machines: a servo-hydraulic load frame to determine the yield strength and ultimate tensile strength and the Rockwell hardness to determine the hardness. The data for each alloy was well recorded after every test done.
We used the following formulae in this lab:

Area reduction Elongation …show more content…

It had the highest elongation of 31.8% followed by material #Sz (steel) which had 25.5% elongation, material #Sx (steel) was ranked third with elongation of 15.96%, in the fourth place was material #Ay with elongation of 16.26% and material #Sy had the lowest elongation of 0.404%. From the tensile test carried out, we proved that material #Sy is the most brittle material. We did hardness test five times and hereunder are the average results shown in table

    The inner moral compulsion to obey is what drives most social organizations. Sykes (2007) described several structural defects that occurred in the New Jersey State prison. Sykes (2007) argues that power in prison is not based on authority therefore prison officials have to find other means to get prisoners to abide by the rules and regulations. The ability to use force to maintain order on a large scale in the prison is an illusion. According to Sykes (2007), Certain privileges such mailing and visiting, personal possessions, time-off for good behavior etc. are given to the inmate all at once upon his or her arrival to the prison.

The first step I am going to take as the new safety manager of Dosit to bring them up to compliance with the Hazard Communication Standard would be to conduct an extensive chemical inventory check. The current chemical inventory list of 780 chemicals is over two years old and is outdated by a year. Periodic chemical inventory audits should be done at least once a year(David Fender,2012).

    The measured tensions were normalized relative to the maximum tension and the lengths were normalized relative to the length at which maximum force was generated (Ln = 29 mm). The measured data and expected data were plotted together (Figure 3). Correlation between measured and expected tensions at the same normalized lengths was determined for the three expected segments of the length-tension relationship.2,3,4 This was done using piecewise linear regression and yielded r2isometric = 0.956033. The fitted curve for the isotonic experiment resulted in r2isotonic = 0.960557. The F0 was 19.5 N for the fit and 6.35 N for the guess.

    Lab 1 helps create a better understand of the changes in crystal structures when the annealing and quenching process is applied to 1020 and 1080 steel. The numbered steel refers to the ASTM grain-size number. Formula 1 is used to solve for the grain size. n=2^(G-1) Equation (1) at 100x magnification Crystal structures change shapes which changes the strength of the material and its properties. The metal might become soft, brittle, hard, or ductile.

    In this experiment, the ions that go through gravimetric analysis are the copper and sulfate ions (Grossie and Underwood, 25). Elemental analysis involves determining the amount, which is usually a percent, of an element present in a compound (Blauch, 1). In this experiment, the element going through the elemental process hydrogen, in which the percent of the compound is attempted to be found (Grossie and Underwood, 25). In order to find the amount of copper, copper oxine needs to be formed. To find it, there is a reaction of hydrated copper sulfate and oxine, producing copper (II) oxine (Grossie and Underwood, 25).

    Deviant behavior is the behavior that is different from the most powerful norms of the society or can also be defined as odd or unacceptable behavior. In sociological way deviance is simply any violation of societal norms. There are many reasons why a person has deviant behavior which includes biological , psychological and sociological explanations. the most popular sociological theories are Structural Strain Theory which was developed by Robert K merton as an addition of the functional point of view on deviance. The theory discovers the origin of deviance that these are caused by the difference

    Properties of Substances Express Lab 1)The purpose of this lab was to compare the physical properties of different types of solids and how the properties of solids are determined by their intermolecular forces and their intramolecular bonds. Then we were to classify each type of solid as either ionic, metallic, non-polar molecular, polar molecular, or network. Paraffin wax classified as a non-polar molecular, Silicon dioxide was classifies as a network, Sodium chloride was classified as ionic, Sucrose was classified as polar molecular and Tin was classified as metallic. (2)The intermolecular forces that are present in Paraffin wax are dispersion forces, because it is non-polar and carries a negative charge. Followed by Sucrose that has

    Table 1: 2024T351 Specimen Experimental Data The experimental ultimate tensile strength of 65,507.15 Psi is relatively close to the typical tensile strength of 64,000 Psi with 2.35 percent error. The experimental young's modulus of 10,644,380 Psi is close to the standard elastic modulus of 10,600,000 Psi with 0.42 percent error. Using the graphs, the yield stress was found using a 0.2% offset. The yield stress was found to be about 50,000 Psi, far from the standard 42,000 Psi. This resulted in a 19.05 percent error.

  • Robert Merton's Structural Strain Theory

    787 Words  | 4 Pages

    The structural strain theory was developed by sociologist Robert K. Merton as part of the functionalist perspective. Strain occurs when individuals find it hard to achieve cultural goals through institutionalized means (Merton, 1938). This theory suggests that there are five responses to strain, which include conformity, ritualism, innovation, retreatism and rebellion (Andersen and Taylor, 2009). The responses are developed based on two factors, which are, first, whether the individual accepts or rejects the cultural goals of the society and second, whether the individual accepts or rejects the instituitionalized means of achieving them. To understand this theory, we first have to understand what cultural goals and the institutionalized means of achieving them mean.

    Abstract The purpose of carrying out this experiment was to investigate the phenomenon of Newtons’s Rings, to gain a better understanding of the theory Newton developed as well as to calculate the radius of curvature of a plano-convex lens and the thickness of a section of optical fibre. The effect is named after Isaac Newton who first studied it in 1717. The pattern observed appears as a series of concentric bright and dark fringes, which has its centre at the point of contact between two surfaces.
