3 Product Life cycle can be divided into various stages like
Development :- It is the incubation or starting step of product cycle. This involves concept generation, design etc
Introduction:- This is the stage when product is introduced into the market
Growth:- This stage consists of rapid increase in sales and revenue.
Maturity :- This is the time when sales are at its peak and the main aim is to hold the market share and plan to increaseproduct life
Decline:- This is when new technology takes over and the product becomes outdated
Chapter 2
1-A manufacturing system can be defined as the arrangement and operation of machines, tools, raw material, personnel and data to produce a value-added product whose success and cost is defined by measurable parameters like profits
Chapter 3
1) c-performance
2) b- static
3) b- Hooke\'s law
4) a- Youngs Modulus
5) c- stress
6) b- strained
7) a- toughness
8) Brinnell, Rockwell, Vicker\'s
9) a- micro structure
10) Heat Capacity is the amount of heat to be supplied to a kilogram of material to raise its temperature by 1 degree celcius
Thermal Conductivity is the amount of heat that a material of unit thickness will conduct across a unit temerature diffference.
