Need for designing
Often, design begin when an individual or company recognizes a need, or identifies a potential market for a product, device of process. Alternatively ‘need’ can be defined as when a company decides to reengineer one of its existing products. The statement of nedd is referred to as the market brief.
Evolution and synthesis of mechanism
This is the process of combining the ideas developed into a form or concept which often potential solution to the design. for mechanical system, possible mechanism or group of mechanism are so selected that will give the desired motion. Basic knowledge of mechanical engineering subjects and creative thinking help in development of mechanisms and assembly.
Force analysis
The force transmitted by the various element of the selected mechanism has to be determined as the stresses induced in the machine member depends on the type and magnitude of the forces. Possible failures are evaluated through the force analysis.
