Mass, motion, forces, energy, design, and manufacturing—these comprise the world of mechanical engineering today. Continual research and development has led to better machines and processes culminating in key events and technological advancements, that have improved the 'quality of life' of mankind. Mechanical engineering is concerned with all aspects—design, development, construction, production, installation, operation and maintenance—of almost everything that we come across in our daily lives-be it a sophisticated jet engine or a simple toy. It is to acknowledge the growing importance of this field IUP has come up with a quarterly journal—The IUP Journal of Mechanical Engineering.

A Typical Approach to Design and Analysis of Foldable Bicycle

--Manash Bhuyan, R Rahman, A Chetia, S Das and S Rajkhowa

Today, due to time shortage and stressful life, people give least importance to exercise and body fitness. To cope with time deficit, bicycle is utilized, but regular bicycles occupy lots of space to park and are not easy to carry around. To overcome these problems faced by the society, an idea is conceptualized to design a foldable bicycle. The main idea of the study is to provide a foldable bicycle which is light and sleek, yet rigid and safe and easy to handle and maintain. A market survey is done to find out the availability of the frame material. Design is developed in SolidWorks 2015 in a HP computer with specifications such as Windows 7 Ultimate, Service Pack 1, RAM 4GB, Processor-Intel i3 4th generation, 64-bit. The proposed design is developed using IS code. A systematic analysis on the relationship between material properties and design for folding bicycle has been studied in STAAD pro V8i, series 4. The techniques applied under present investigation will definitely help the rider in his daily life.

Design and Analysis of a Steam Engine Turbine Rotor

--N Balasubramanyam and H C Chittappa

Simulation-driven design processes are verified and optimized with the support of computer-based product model simulations. The paper deals with modal analysis and harmonic analysis of the 40 MW steam turbine rotor to find out the natural frequencies and mode shapes using ANSYS. Based on the theoretical design considerations, the critical speeds and amplitudes in the rotor of the steam turbine are derived.

An Experimental Investigation of Mechanical and Microstructural Properties of Friction Stir Welded Dissimilar Joints of Aluminum Alloys with Square Tool Pin Profile

--Malwinder Singh, Khushdeep Goyal and Rakesh Bhatia

The paper investigates the mechanical and microstructural properties of friction stir welded joints of dissimilar aluminum alloys. The square tool was used to perform the friction stir welding operation. The maximum tensile strength is obtained at rotational speed of 800 rpm and welding speed of 30 mm/min. It was found that with the increase in tool rotational speed, tensile strength of welded joint increased at 800 rpm. At tool rotational speed of 800 rpm, the tensile strength decreased with increase in welding speed. The microhardness of friction stir zone decreased with decrease in welding speed. The microstructure revealed a dense welded zone without any defect. It was observed that the weld material was defect-free.

Manufacturing, Experimental and Finite Element Analysis of Composite Material Ceiling Fan Blade

--P K Desai and P G Patil

In this paper, an effort has been made to study the performance and characteristics of existing ceiling fan blade using Finite Element Analysis (FEA) of composite material ceiling fan blade. An experimental analysis is carried out using Fast Fourier Transform (FFT) analyzer to check out the vibrations and power saving, in comparison with conventional fan blade. This indicates that composite blade has more strength over the existing fan blade. The composite fan blade reduces the weight of fan blade, which is 28% lesser than the existing blade and 30% of power consumed. The paper determines the usage of composite material as an alternative for ceiling fan blade.

An Investigation of Thermal Impact in the Manufacture of a Connecting Rod

--S S Sonigra

The effect of temperature variation during manufacturing of the connecting rod affects the dimensional quality of the product. The paper presents a case study for the rejection of the lot by the customer. A big lot was rejected by the customer because of the oversize of various parameters. The problem is discussed in detail with the readings of various parameters. The rate of thermal expansion plays a considerable role to have dimensional accuracy at micro level. Two methods are described to overcome the problem. The correction factor is found out by taking various readings of the dimension at various temperatures. Both methods are implemented as per need. The pros and cons are discussed and solutions are suggested.

Automated Teller Machines (ATMs): The Changing Face of Banking in India

Bank Management
Information and communication technology has changed the way in which banks provide services to its customers. These days the customers are able to perform their routine banking transactions without even entering the bank premises. ATM is one such development in recent years, which provides remote banking services all over the world, including India. This paper analyzes the development of this self-service banking in India based on the secondary data.

The Information and Communication Technology (ICT) is playing a very important role in the progress and advancement in almost all walks of life. The deregulated environment has provided an opportunity to restructure the means and methods of delivery of services in many areas, including the banking sector. The ICT has been a focused issue in the past two decades in Indian banking. In fact, ICTs are enabling the banks to change the way in which they are functioning. Improved customer service has become very important for the very survival and growth of banking sector in the reforms era. The technological advancements, deregulations, and intense competition due to the entry of private sector and foreign banks have altered the face of banking from one of mere intermediation to one of provider of quick, efficient and customer-friendly services. With the introduction and adoption of ICT in the banking sector, the customers are fast moving away from the traditional branch banking system to the convenient and comfort of virtual banking. The most important virtual banking services are phone banking, mobile banking, Internet banking and ATM banking. These electronic channels have enhanced the delivery of banking services accurately and efficiently to the customers. The ATMs are an important part of a bank’s alternative channel to reach the customers, to showcase products and services and to create brand awareness. This is reflected in the increase in the number of ATMs all over the world. ATM is one of the most widely used remote banking services all over the world, including India. This paper analyzes the growth of ATMs of different bank groups in India.
International Scenario

If ATMs are largely available over geographically dispersed areas, the benefit from using an ATM will increase as customers will be able to access their bank accounts from any geographic location. This would imply that the value of an ATM network increases with the number of available ATM locations, and the value of a bank network to a customer will be determined in part by the final network size of the banking system. The statistical information on the growth of branches and ATM network in select countries.

Indian Scenario

The financial services industry in India has witnessed a phenomenal growth, diversification and specialization since the initiation of financial sector reforms in 1991. Greater customer orientation is the only way to retain customer loyalty and withstand competition in the liberalized world. In a market-driven strategy of development, customer preference is of paramount importance in any economy. Gone are the days when customers used to come to the doorsteps of banks. Now the banks are required to chase the customers; only those banks which are customercentric and extremely focused on the needs of their clients can succeed in their business today.
