Fracture Mechanism In Design And Failure Analysis
Introduction
 Separation of solid into two or more pieces under applied load or stress
 Applied load or stress may be tensile or compressive in nature
 Fracture due to
1. Crack initiation
2. Crack propagation
Principles of Fracture Mechanics
 Quantitative study of failure is called fracture mechanics
 Fracture mechanics is the relationship between
 Material properties
 Stress level
 ....etc

RADIO FREEQUENCY CONTROLLED, ROBOT

DESCRIPTION


A TE trigger the 3encoders are a series of CMOS LSIs for remote control system applications. They are capable of encoding 18 bits of information which consists of N address bits and 18_N data bits. Each address/data input externally trinary programmable if bonded out. It is otherwise set floating internally. Various packages of the 318encoders offer flexible combinations of programmable address/data to meet various application needs. The programmable address/ ....etc

TO DESIGN & FABRICATE A SIX SLOT GENEVA WHEEL MECHANISM
INTRODUCTION
The Geneva mechanism is a timing device. It is used in many counting instruments and in other applications where an intermittent rotary motion is required. Essentially, the Geneva mechanism consists of a rotating disk with a pin and another rotating disk with slots (usually six) into which the pin slides. The Geneva mechanism was originally invented by a watch maker. The watch maker only put a limited number of slots in one of the rotating disks ....etc

Introduction
In this tutorial you create a slider crank mechanism using a combination of revolute and
cylindrical joints. You will also experiment with additional plotting utilities in CATIA.
1 Problem Statement
A slider crank mechanism, sometimes referred to as a three-bar-linkage, can be thought
of as a four bar linkage where one of the links is made infinite in length. The piston based
internal combustion is based off of this mechanism. The analytical solution to the
kinematics of a slider crank can be found in elementa ....etc

Abstract ” In other to save energy, several countries recently made laws related to standby power consumption. To success this exertion, we should consider not only power reduction of consumer electronics itself but also efficient automatic control in networked home environment. In this paper, we present a design approach and implementation result of control mechanism for standby power reduction. Proposed mechanism has the Host-Agent based structure and uses the IEEE 802.15.4 based ZigBee protocol for communication and security between H ....etc

Study on the Mechanism and Locomotion Strategy
for New Snake-Like Robot Active Cord Mechanism


This paper presents ACM-S1 (Active Cord Mechanism
- Slime model 1), a snake-like robot. Conventional
snake-like robots have difficulty negotiation uneven
ground. In this paper, we propose “a bending
and expanding joint unit” which has three degrees
of freedom (3DOF) in inchworm/angleworm-like
motion and has been developed to solve this problem.
The ACM-S1 we developed is composed of a series
of these joint units. ....etc
