The design of the crankshaft considers the dynamic loading and the optimization can lead to a shaft diameter satisfying the requirements of automobile specifications with cost and size effectiveness. The review of existing literature on crankshaft design and optimization is presented. The materials, manufacturing process, failure analysis, design consideration etc. of the crankshaft are reviewed here.

In the present work,a data matrix comprising of 10 attributes and 10 alternatives is presented .It is then operated for optimum selection in form of ramking using one of the welknown Multi Attribute Decision Making( MADM) method called Technique for Order Preference by Similarity to Ideal Solution (TOPSIS).The results are given as ranking for the purpose of selectionwhich sets initiative for preliminary design.However the approach presented is also useful for existing designs which needs to be changed to enhance performance.

In column or beam there are many horizontal and vertical rods to support the concrete, they are required to be tied together so that they give enough strength to the structure. Square or any trapezoidal shape stirrups are used to tie rod together by means of tight wires. In small construction sites workers bend stirrup using traditional way. There is no other way to make stirrup with less human effort. And for this reason automation is required which is the objective of the project presented. It is possible to decrease construction lead time with increase of the stirrup bending rate by automation only. Here an attempt is made to design and develop an " Automated Stirrup Bending Mechanism " (ASBM) using the principles of hydraulics and electronics. Its use reduces a lot of labour cost, effort and construction lead time and production of various sizes of stirrup and accuracy increases.

MR brakes are smooth acting, simple construction and easily controllable. The MR fluid has properties of non Newtonian fluid in normal condition and its rheological properties can be changed by applying the magnetic field. It again becomes fluid by removing the magnetic field. The MR fluid brake transmits torque by shearing of MR fluid in absence of applied magnetic field as suspended particles can not resist relative motion but when the magnetic field is formed by passing an electric current the suspended particles arrange themselves to form chain like structure in the direction of magnetic flux path and increases shear stress of fluid and gives enough resistance. The braking torque value depends on magnetic field strength. The present paper is based on MR fluid filled in peripheral as well as side gaps between rotor and casing thus giving more effective braking torque. An attempt is made to design such a brake an...

The area of tribology i.e. the science of friction, wear & lubrication deals with designing the equipments for the same. Moreover, in this, there is little information available in the literature for the purpose of carrying out the experiments to assess the various parameters of friction, lubrication and wear. Most of the research literature deals with the specific design of experimental set up to suit the requirement of the investigation to be made. An overview of the experimental techniques is presented in order to study the common or garden equipment of commerce. Some of the research methods are briefed at the end.
