SIMPLE MECHANISM 

Kinematics link Or Element:- Energy part of a machine which is having some relative motion with respect to other part is known as kinematics link Or element. 

NOTE:- It is very necessary for a link to be a resistant body. A resistant body is capable of transmitting power from one element to other.
 
A link may consist of one or more resistant bodies. 

Types of Link

1. Rigid Link:- link in which deformation is negligible is known as rigid link. 

Example:- Crank, Connecting Rod, Piston etc. 

2. Flexible Link:- The link in which deformation is observed but under permissible limit is known as flexible link. 

Example:- Rope drive, Chain drive, Belt drive. 

3. Fluid Link:- The link transmitting power with the help of fluid is known as fluid link.
 
Example:- Hydraulic press, Hydraulic brake, Hydraulic coupling etc.

  (b) CERAMIC MATERIALS:- - Ceramics usually consist of oxides, nitrides, carbides, silicates or borides of various metals.  - Ceramics are any inorganic, non-metallic solids (or super-cooled liquids) processed Or used at high temperatures.  - Ceramic materials are rock or clay mineral materials.  - Ceramic materials contain compounds of metallic and non- metallic elements, such as MgO, Si02, SiC, BaTiO3, glasses, etc. Such compounds contain both ionic and covalent bonds.    - Important characteristics of ceramics are :   (i) Brittleness   (ii) Rock-like appearance  (iii) Resistance to high temperatures  (iv) Hardness   (v) Abrasiveness   (vi) Insulation (to flow of electric current)  (vii) Corrosion resistance   (viii) Opaque to light   (ix) High temperature strength.  - Examples of ceramic materials are :  (i) Sand                  ...

Project planning and CPM

Network Definition:- A business network is a Complex network of companies, working together to accomplish certain objectives. These objectives, which are strategic and operational, are adopted by business network based on their role in the market.                             There are two categories of business network, business association and company aggregation. Project Planning:- The project planning is the categorization of the activities involved in project implementation in a sequential order followed by a schematic presentation of the activities necessary for the entire project. Types of Project Planning:-  1. Event and Activity 2. Dummy Activity 3. Slack 4. Arrow What is CPM:- Critical path method (CPM) developed in the 1950 is an algorithm needed for planning arranging, scheduling, coordinating and governing of a project.                   ...

What is theory of machine:- It is define as the branch of engineering science. Which deals with the study of relative motion between different parts of machine. What is machine:- It is the combination of different mechanism which convert one form of energy in to useful work. Need and importance of theory of machine:- It is the branch of engineering mechanics which deals with the study of motion, without considering the case of motion, i.e. force. 1. Kinematics 2. Dynamics 1. Kinematics:- It is that branch of theory of machines which deals with the relative motion between the various parts of machines. 2. Dynamics:- It is that branch theory of machine which deals with the forces and their effects, while acting upon the machine parts in motion. There are two types of dynamics. 1.Kinetics 2. Statics  1. Kinetics:- It is that branch of theory of machine which deals with inertia forces which arise from the combined effect of the mass and motion of the machine parts...
