ABSTRACT

In the vibrating beam experiment, an aluminum cantilever beam was made to vibrate. An accelerometer transducer was used to convert the mechanical vibrations into a signal that was fed into an oscilloscope via a power supply. The oscilloscope mapped the signal into a sine curve and displayed it on the screen.
The oscillations’ decay curve was studied and the beam’s damping ratio was determined. The decay curve’s logarithmic decrement was used to determine the beam’s damping ratio and its natural frequency.
The beam’s damping ratio was observed to be underdamped at a damping ratio of 0.0066.

Experiment 13

Simple Harmonic Motion
Introduction
The purpose for this experiment was to measure spring’s constant of a spring. In part 1, extension of the spring when a mass is hanged on it was measured. Six measurements for the extension were obtained for each mass used. All the measurements were used to determine the spring’s constant by plotting a graph of weight against extension. In part 2, six measurements of period were taken using different masses (same masses used in part 1). The measurements were then used to plot a graph of square of periods against mass. The equation of the ...

Oscillatory Motion

Introduction
The purpose of the experiment was to evaluate the spring constant of a spring connected to mass and to determine the effect of varying mass on the period of oscillation. It was hypothesized that the increase in mass would lead to increase in the period of the oscillating spring.

Theory

Hooke’s Law
According to Hooke’s law, the restoring force (F) of a stretched spring is proportional to its extension (x) (Mansfield and Colm, 39).
F ∞ x
F = - k x

Where F is the restoring force, x is the extension and k is a constant of proportionality called spring constant.

The negative sign indicate that the direction of restoring force is opposite that of extension.

Introduction

Tension forces act on liquid surfaces, the thread in them is pulled into circular arcs. The pull is referred to as surface tension of the liquid. Surface tension exists uniformly in all directions. The forces affect the shape and motion of liquids that have open surfaces. Tension forces can be understood regarding forces that occur between the molecules. Repulsion occurs in molecules when they are close but attract when they are far from each other. Inside the liquid, molecules are close to each other. Thus, there are slight repulsions. Molecules at the surface of the liquid are some distance ...

The holiday plays a role in the process of socialization of the person, the perception of his role and relationship to social groups.

Analysis of a Quotation from T. S. Eliot’s “The Waste Land”

April is the cruelest month, breeding

Memory and desire, stirring

Dull roots with spring rain.
Winter kept us warm, covering
Earth in forgetful snow, feeding
A little life with dried tubers. (Eliot)

T. S. Eliot’s renowned poem “The Waste Land” denotes his dissatisfaction with the state of modern life in general, a work that mirrors the degraded confusion of the WWI ravaged Europe. It utilizes the integration of mythology into his poetic expression, with numerous references, which result in a narrative that is almost lacking in coherence. His introductory lines offer a glimpse into his dark pessimism that ...

Introduction

Bend (flexure) testing is often done in springs as well in brittle materials whose behaviors of failure are linear like concrete, wood, plastic, glass and ceramics. Bend testing is suitable for evaluating the strength of brittle materials where the results of tensile tests aren’t easy to interpret due to the breaking of specimens around the gripping (Schoffstall, Charles, and Robert 234). In bend testing experiment, smooth rectangular specimens without notches are recommended under three or four point bend arrangements. Figure I below illustrates three point and four point bend arrangements respectively.

Introduction

The discovery of restriction enzymes (REs), bacterial transformation, and agarose gel electrophoresis caused the sudden increase of popularity of molecular biology in the 1970s. Restriction enzymes allow the manipulation of specific sites of an organism’s genes and are commonly used in many laboratories worldwide. Restriction enzymes cut DNA in many different ways and can produce sticky ends and blunt ends (Weaver, 2012). The most abundant type of restriction enzymes is Type II, which require magnesium cations as cofactor (Pingoud et al., 2005). Aside from their popularity is recombinant DNA technology as a “cut and paste” tool, estriction enzymes can ...

Salmon Fish

The Atlantic salmon fishes are known for their strong, streamlined bodies and their ability to move through steep rivers in fresh and salt waters as their habitat (Jonsson and Jonsson 2). The term “Salmo” is a Latin term which means salmon that originated from the word “salar” which means to leap. The Atlantic salmon are anadromous which means that they spawn in freshwater and acquire most of their food while they explore the marine habitats (Jonsson and Jonsson 2).
The management systems used for production of transgenic Atlantic salmon is similar as those that are being presently used for non-transgenic ...

Patterns of Surface Ocean Currents

Surface currents are found in the upper four hundred meters of an ocean body and they form major patterns such as eddies, upwelling, and gyres (Garrishon, 2007). Surface currents result from wind energy that is concentrated in both north and south hemispheres forming trade winds which are easterlies and westerlies (Garrishon, 2007). Waves on the sea surface transfer some of the energy from the moving air to the water by friction. Pulling of wind on the surface of ocean causes an accumulation of water with the water displaced underneath the wind forming the movement.
