Helical Gear
What is helical gear ?
Helical gear is the type of gears .
Helical gear is a cylindrical shaped gear with helicoid teeth. Helical gears operate with less noise and vibration than spur gears .
Helical gears can be meshed in a parallel or crossed orientations.
The angled teeth engage more gradually than do spur gear teeth causing them to run more smoothly and quietly
Types of Helical gear-
1. Cross helical gears
Crossed Helical Gears ....etc

1.0 INDRODUCTION
An escalator is a moving staircase conveyor transport device for carrying people between floors of a building. The device consists of a motor-driven chain of individual, linked steps that move up or down on tracks, allowing the step treads to remain horizontal.
Escalators are used around the world to move pedestrian traffic in places where elevators would be impractical. Principal areas of u ....etc

Gears, Gears and More Gears
What is a gear?
A gear is a wheel with teeth that mesh together with other gears.
Gears change the
• speed
• torque (rot. force)
• direction of rotating axles.
Different types of gears
Spur gears
Idler gears
Worm gears
Bevel gears
Belts & Pulleys
Spur Gears
Most “common” type of gear, a wheel with teeth
Spur gears do three things.
1. Change rot. speed
2. Change torque
3. Change direction
Make sure there isn’t too much friction between th ....etc

SEMINAR REPORT ON TOOL COMMAND LANGUAGE
Introduction to Tcl
TCL/TKs (Tool Command Language/Tool Kit) strength is that it is a small, interpreted, language that can be embedded, access graphics and system features, and is extensible. It also is multiplatform and has very wide support. It can be downloaded on the NET, and it runs TCL scripts for backend processing. TCL is a language, called the Tool Command Language. TK is a set of extensions or widgets(the actual official designation) that happened to be written by TCL� ....etc

FINITE ELEMENT ANALYSIS OF A GEAR TOOTH USING ANSYS AND STRESS REDUCTION BY STRESS RELIEF HOLE
ABSTRACT
 The main aim of this project is to model a spur gear by PRO-E. The model is then imported to ANSYS
 To reduce the stress in a gear tooth, with the help of a stress relief hole, to the minimum value, without affe ....etc

DESIGN, FABRICATION AND PERFORMANCE EVALUATION OF GARDEN TILLER

ABSTRACT
In order to meet the food requirements of the growing population and rapid industrialization, modernization of agriculture is inescapable. Mechanization enables the conservation of inputs through precision in metering ensuring better distribution, reducing quantity needed for better response and prevention of losses or wastage of inputs applied. Mechanization reduces unit cost of production through higher productivity and input conservation.
The p ....etc

Graph separation is a well-known tool to make (hard) graph problems accessible to a divide and conquer approach. We show how to use graph separator theorems in combination with (linear) problem kernels in order to develop fixed parameter algorithms for many well-known NP-hard (planar) graph problems.
We coin the key notion of glueable select verify graph problems and derive from that a prospective way to easily check whether a planar graph problem will allow for a fixed parameter algorithm of running time for constant c.
Besides, we introduc ....etc

Introduction

I/O-efficient graph algorithms have received considerable attention lately because massive graphs arise naturally in many applications. Recent web crawls, for example, produce graphs of on the order of 200 million nodes and 2 billion edges. Recent work in web modeling uses depth-first search, breadth-first search, shortest paths, and connected components as primitive operations for investigating the structure of the web.

Massive graphs are also often manipulated in Geographic Information Systems (GIS), where many fundamental ....etc

ABSTRACT
Hydraulic systems provide a means of remotely controlling a wide range of components by transmitting a force through a confined fluid.
Because hydraulics can transmit high forces rapidly and accurately along lightweight pipes of any size, shape and length, they are the prime source of power in aircraft systems such as flying controls, flaps, retractable undercarriages and wheel brakes.
Modern aircrafts include many different types of subsystems. These subsystems are very closely interlinked t ....etc
