Draw and annotate a stress strain curve of a polymer

Characteristics of polymers:

1. High corrosion resistance

2.Lower density

3.Cost of production is low

4.Specific strength is high.It means that weight to strength ratio is high that is why polymer light in weight.

5.Polymer can be handle easily

6.Polymers have resistance to thermal and electric conductance.

The categories of polymers

1. Elastomers

2. Brittle plastics

3.Plastics

The strain stress curve for different polymers.

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
