mechanical fasteners… Threaded
Two very basic types of machine-threaded fasteners are
– nuts & bolts and screws.
Their great advantages include the
– ease of assembly, which generally requires no special equipment, as well as
– the possibility to de- and re-assemble without (much) damage to the joint.
– They may be used for most materials.
Screws and bolts are made in a wide range of materials, with steel being perhaps the most common, in many varieties. ....etc

1. INTRODUCTION
Connections are structural elements used for joining different members of a structural steel frame work. Any steel structure is an assemblage of different members such as beam, columns, and tension members, which are fastened or connected to one another, usually at the member ends. Many members in steel structures may themselves be made of different components such as plates, angles, I beams, or channels. These different components have to be connected properly by means of ....etc

I need working of dark sensor using LDR and LM324 ,no transister used.

The LM324 is a 14 Pin dual in-line Plastic Package chip which has four independent, high-gain, internally frequency compensated operational amplifiers (Op-Amp) designed to operate from a single power source. It is also possible to power this with 4 different power sources….One for each independent Op-Amp inside the chip. This chip can be used as a Power Amplifier , LED Driver , “BI-QUAD” RC Active Bandpass Filter , Lamp Driver , Pulse Generator , Square wave Oscil ....etc

BLOCK SHEAR FAILURE IN TENSION MEMBERS
ABSTRACT
Block shear is a limit state that should be accounted for during the design of steel tension members. This failure mechanism combines a tensile failure on one plane and a shear failure on a perpendicular plane. It is important for a design equation not only to predict the capacity reliably, but also to predict accurately the failure mode.
In this study, we begin with an overview of tension members, their behaviour and design strength which is affected by yielding, fracture or ....etc

Study and Modeling of the Mechanical Behavior of Hexagonal Metals

Introduction
Hexagonal close-packed (hcp) metals deform plastically by a variety of slip and twinning modes. The relative contribution of these mechanisms depends strongly on the material studied and the conditions, such as temperature, under which the deformation is performed. This work further elucidates the complicated competition and interactions between twinning and slip deformation modes for two hcp materials, namely zirconium and magnesium. The model presented here to ....etc

STRUCTURAL DESIGN OF DRYDOCK FRONTAGE DREDGING SYSTEM

EXECUTIVE SUMMARY
In the present era of globalization, transportation has an important role, being the cheapest mode of transport, ships and boats contribute much to business and industry. Their repair maintenance and manufacturing are carried out in docks. The moment of floating crafts towards and outward the dock faces the problem of mud deposits on the path. In order to maintain an accident free dock, these mud deposits are to be removed off periodically. This pro ....etc

DESIGN OF BOILER STACK
ABSTRACT
Chimney, which form the last component of a system using a flue gas such as feoiler, IC engines, play a vital role in maintaining efficiency, draft, etc, of a system and also in minimizing the atmospheric pollution.
The boiler plant of HOCL had used LSHS (low Sulphur heavy stock) as a fuel. Recently they changed the fuel to LSFO (low Sulphur furnace oil). As a combined effect of increased corrosion rate and natural calamities the stack had undergone failure. As per the Kerala State Polluti ....etc
