Displacement Reports Samples For Students

Abstract

This lab study was undertaken to analyze the effects of torque forces and shear modulus of rigidity on three circular solids namely, half-hard brass (60% Cu and 40% Zn), 0.1% and 0.4% carbon steel. This was done by subjecting the samples to a shearing stress and by noting down its angular displacement. The maximum torque of each sample was calculated and compared. Their polar moment of inertia was also calculated to assist in analysis. The value of shear modulus of rigidity of each of the samples was determined using a graph which related torque and angular displacement. It was ...

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 ...

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.

Introduction

Beams are very crucial elements in engineering structures. They carry the loads and the weight of the structure and then transmit them to the supports . There are various types of beams configuration that engineers must select depending on the application. These include simply supported beams, cantilever beams and curved beam amongst others. Curved beams are very common in complex structures such as bridges, forklift hooks, crane hooks and in many other applications. Analysis of curved beams is complex compared to that of cantilever and simply supported beams. Thus, in order to enhance the structural integrity of the structure, engineers ...

Wavelength and Frequency

In this experiment, the frequencies are recorded at high certainty values. The increased certainty in these values is due to the high precision of the Amplitude knob. It takes only a few seconds to change the frequency before an effect is seen.
When the experiment is repeated for a standing wave with two wavelengths, we get different results. The two-segment waves vibrate with a node at each end and one note in the middle such that the wavelength is equal to the length of the string used in the experiment. The frequency of two segment wavelength is about twice ...

Theory and Operation
1. Black Direct Acting Pressure Relief Valve
This lab is used to analyze the action of various values by disassembling and assembling. This valve is used to describe its action in the hydraulic circuits.

Action of Black Direct Acting Pressure Release Value

The relief valve acts as the fuse or circuit breaker in an electric circuit. An electric circuit blows a fuse unless it overloads. The hydraulic circuits allow the relief value to dump. Protecting the pump from the excess pressure is the main function of a relief valve. The direct acting relief value responds quickly to the pressure tries to go and observe ...

Introduction

A pendulum consists of a bob or point mass which is suspended from a light string tied at one end to a pivot point. The string is assumed to have negligible mass.1 If the point mass of the pendulum is pulled to a small angle from vertical plane and released, it will swing back-and-forth at a regular period and frequency. Time taken by the pendulum to make one full back-and-forth swing is termed as period of a pendulum. If the amplitude of motion or swing is small, motion of a simple pendulum is like simple harmonic motion and can be approximated by

Lab report #4
Section 214

Objective:
Hook’s is a fundamental topic of physics and few divisions of engineering like Civil and Mechanical engineering. This law helps to perceive elastic property of a material. As per this principle of physics, force needed to compress or extend a spring by some amount of distance is proportional to the distance. If F is force and x is distance, then as per Hook's law, F = -k.X, where k is termed as stiffness and it is constant for a material rather the spring. Purpose of this experiment was to find spring constant (k).

Lab- Accumulator

Purpose
The purpose of this lab report is to understand the working of accumulator machine in the various working environment.
Theory
A useful application of the accumulator is to provide the ready source of the hydraulic power; thus the pump is running constantly. This application permits the small pump and the accumulator are to deliver a high output for the required intervals of time. The pressure switch is being used to charge the accumulator in the pressure level. The hydraulic solid pressure is sufficient for this operation. The regular piston accumulator is used as the mounting bar. ...

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 to Wave

Wave motion is known as transfer and moving energy from one point to another, wave is also referred as oscillation or disturbance that travels along the matter or space. There are two categories of waves they include transverse and longitudinal waves. In longitudinal wave particles of the medium are displaced in a direction parallel to the energy transferred while in a transverse wave particles of the medium are displaced in a direction perpendicular to the direction of energy transferred (Hewitt & Paul, 35).
Waves can be moved along ropes across the surface of strings and water. Some waves can travel through space. ...

Introduction

Global warming is defined as the high and rising rate in the average level of temperature in the atmosphere of planet earth as well as in large water bodies such as oceans (climate system). The extreme variation in temperature began in the earlier times of the 20th century and it is anticipated to further increase in the coming years. This change in the global mean temperature on the earth’s surface is approximated at 140 F which is equivalent to 0.80 C. Increasing temperatures have greatly contributed to the climate change of various parts of our planet earth. In ...

INTRODUCTION

Physical activity is a much smaller priority among youth in America and other countries, including the UK (Brockman et al., 2010). These habits of a sedentary lifestyle most often translate into inactivity as an adult as well, increasing the risk of mortality and disease (Gustafson and Rhodes, 2006). Obesity and cardiovascular disease is often linked to inactivity in children, causing significant health problems for youth around the world (Cleland and Venn, 2010). More successful interventions promoting physical activity in youth must be found and implemented if youth health is to be improved.

Active play is one method in which physical activity ...
