Abstract

In this experiment, the young modulus of three beams was investigated these were steel, aluminum and timber. The beams were placed and the deflections values upon addition of various loads at the Centre of the beam taken. There was a variation of the loads across the beam to investigate thee relationship that existed between the loads, the span width, height, and deflections. Measurement of the deflection was therefore done through the dial gauge with three sets of measurements being taken and the average calculated. Different beams were used to enable elaborate comparison of the coefficient of elasticity. Measurement of ...

Abstract

The aim of this experiment was to determine the relationship between the Young’s Modulus and the deflection of a beam. Since different materials have different values of Young’s Modulus, the students selected three different materials for the experiment. In this case, the materials used include timber, aluminium, and steel. All the materials were identical in terms of the dimensions such as width and length. The each beam of the three materials was subjected to some magnitude of force at the centre and deflection measured. Data concerning the magnitude of load and the corresponding defection were then gathered ...

Abstract

In this lab, an RC circuit was set up and powered using a square wave from a function generator. The output was manipulated and examined and the results viewed on an oscilloscope. On the oscilloscope, the energy was seen in the way it is stored, delivered and manipulated in circuit elements.

Theory

In our experiment, we study the interference of light using coherent, monochromatic light and two slits. The two slits, separated by a distance d, act as two light sources and their light waves interfere. The light passing through them is captured on another slide kept at a distance D. Here we see the interference pattern consisting of alternating bright and dark light. This effect is seen as the light waves from the two sources meet in phase (increased amplitude) and out of phase (decreased amplitude) creating the bright and dark spots. If hm is the distance of the mth bright band ...

Oscilloscopes and Graphing Multimeters

An oscilloscope is a visual voltmeter that shows a timer on voltage change. There can be different types of Oscilloscopes like analog, digital. Analog uses a CRT (Cathode Ray Tube) screen to display the electrical signals. A digital Oscilloscope uses liquid crystal display and works through storing the incoming signals over a period, therefore, it is also known as a Digital Storage Oscilloscopes (DSO). The data in DSO is presented in a waveform by mapping all the data stored by the DSO. DSO can also be connected to an output device and help in the diagnosis of problems. DSO ...

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.
Figure 1. Bend testing of a smooth ...

Introduction

Numerous electrical applications require an inverter, which converts Direct Current (DC) to Alternating Current (AC) power. Some of these applications require the stepping down of voltage levels when realizing this conversion, which signifies that the input DC power is greater than the AC power. Conversely, certain applications require the opposite: to step up voltage when performing the power conversion, which means that the input DC power is lower than the AC power. These requirements can be met through the use of Voltage Source Inverters and Current Source Inverters, respectively. However, some particular applications require to step down voltage for ...

Abstract

Flexible pavement distresses are caused by poor design, wear and tear, and traffic loading beyond design capacity. The amount of loading that a pavement can bear without failure is determined by the strength of the subgrade and the surface layer. Pavement failures are of eight major types; potholes, bleeding, alligator cracking, rutting, shoving, depression, block cracking, and longitudinal cracking. Each pavement distress has causal gents and repair methods defined by local and international codes. This report shall focus on bleeding, potholes, and alligator failure.

The era following the Victorian time was the Edwardian time. This was an era within the UK when Edward VII was in power. The duration encompassed the historic Titanic sinking, the beginning of World War I in 1914, and the stop of World War I in 1918. This period was marked with great attention in travel and art within continental Europe and was possibly because of Edward VII love of tour. The era brought about an innovative form of art that was known as Art Nouveau. The artistic expression was coupled with highly-stylized, curvilinear designs, flowing frequently incorporating floral ...

Introduction

Brassica rapa, more commonly known as field mustard is part of the taxonomic group Family Brassicaceae. According to the Wisconsin Fast Plants Program, B. rapa is a rapidly-cycling species or a fast plant. This plant was believed to have originated from the highlands near the Mediterranean Sea (Tsunoda, 1980 as cite by Rakow, 2004). Nishi (1980, as cited by Rakow, 2004) reported that this species rapidly grows under low temperature conditions. According to Warwick and Francis (1994), B. rapa extensively grows to coastal lowlands, plateaus, hills and montane regions having an elevation of up to 2300 meter above sea level. Typically, ...
