中文Process Design for Connecting Rod and Main Bearing
RESUME The paper discusses the machining process for a connecting rod of a passenger car and the main bearing of a horizontal wind turbine of 2 MW capacity. For each component, details such as a brief introduction to the product, its use, material used for the component, machining sequence, machine details and pictures and the […]
Critique of a Published Journal Article of Finite Element Method
INTRODUCTION Roque (2000) has performed a simulation using the finite element method for cold forging of a ring of material DIN 16MnCr5. Software application used is ANSYS. The upsetting process was modelled using algorithms developed from previous research. The goal of the paper was to understand the material flow and the potential for die filling […]
Heat shields for spacecraft re-entry and turbochargers for engines
EXECUTIVE SUMMARY Selection of materials for high performance applications is a challenge that industries try to meet with extensive research. The challenge lies in understanding the forces, temperature and pressure that various components are subjected to. Any wrong selection can often result in part failure and other consequences. CES repository provides a very good archive […]
Ethical Energy for Belina: Karsson’s Initial Rocommendations

Belina’s proposed energy policies stand a chance of handling its latest needs in an appropriate matter that serves the people, especially those that have been neglected in previous policy decisions. 2. Transferable technologies that attract local investment in local business are important and they help foster strong international commercial relationships for […]
Horizontal-Axis Wind Turbine Reliability Analysis
Abstract This study attempts to present an analysis of wind turbine reliability through time, specifically the Horizontal-axis wind turbine by collecting studies which were based on surveys and/or simulations. The collected studies focused on failure rates to understand the reliability behavior of wind turbines. To give an overview, a very brief history wind turbines is […]

Requirement # 1 Based on the completed Helicopter Systems Engineering table for Version B, as shown in the Appendix 1, and given the following budget systems engineering allocation: A total capability index of 950 A total development cost of £400 million A unit manufacturing cost of £26 million A development timescale of 36 months A […]
Stress Analysis
1. Problem Description: To analyze a simply supported pipe structure which has three operating forces acting on its top surface. There are three design options / pipe sections available to select for final manufacturing. The selection has to be made based on analytical calculations in terms of meeting performance requirements due to operating loading conditions. […]
ECO-FRIENDLY PRODUCT – Small Scale Hydropower Turbines
(A) INTRODUCTION AND PROBLEM DESCRIPTION The eco-friendly product concepts that shall be outlined are relating to providing solutions for electricity provision to remote landlocked communities. These communities may be in developing or developed countries. The assumption will be that it is too costly, financially and environmentally, to bring grid-based electricity to these communities. The typical […]
Principles of operation and the state-of-the-art a 'novel' sensor/actuator technology
Abstract Sensors and actuators have been around for a long time. Their use was undervalued at some point in time but nowadays they found their way in practically everything. One of the main things would be game controllers which is as popular as mobile phones. With the advent in technological advances, extreme competition in the […]
Combined Heat & Power (CHP)
Abstract The conventional power generation systems end up creating heat energy in huge quantities as they go about the process of converting fuel into electric power. For the average utility-sized power plant, more than two-thirds of the energy content of the input fuel is converted to heat. Combined heat and power systems capture the heat […]

PRODUCT MANAGEMENT, QUALITY MANAGEMENT & INTELLECTUAL PROPERTY
SECTION A I attended Worcester Crown Court on Wednesday 11th February 2009. I arrived at the Court at approximately 1.30pm. Upon arriving I viewed the hearing lists on both the boards and the monitors. No specific times were given for any particular hearings so I asked at the court desk whether there were any hearings […]
Introduction to Mechanical Science
1. An internal combustion engine is an object which converts the chemical energy of the fuel into mechanical kinetic energy. Internal combustion engines have complex thermal cycles which convert this energy. Initially the fuel is burned which converts the chemical energy into thermal energy. The increase of thermal energy is equivalent to an increase in […]
Scaling effect on friction drag of car
Introduction In fluid dynamics drag is the resistance force acting on a solid body moving in a fluid (liquid or gas). Drag is constituted off frictional forces acting in a direction parallel to the body plus the pressure forces acting perpendicularly on the surface of the body. For any solid object moving through any fluid, […]
Design: Speed Controller
2. Product Design Specification: Speed Controller In order to increase on site efficiency a more effective method of removing waste from apartment construction sites is needed. It is desired that a load of 100kg can be removed at a time, efficiently but slowly and with enough control to not create any safety concerns. The starting […]
Errors and Uncertainty in Experimental Measurements
Objective: The aim is to explore and examine how to handle errors and other problems associated with making experimental measurements. This will be carried out through a series of activities involving simple scenarios to conduct numerous trials in and apply statistical methods for analysis. Apparatus: Activity 1: Two paper aeroplanes and additional material for design […]
