Engineering Materials- Module 2 -Activity 1

1. Why pieces of cast iron can not be bent? What are the properties that the material should have in order to be bent?



2. Give examples of situations where the material is subjected to tensile, compression and shear stress.



3. Classify the materials; lead, rubber, steel, and concrete under headings elastic, plastic, and brittle.

1) because its not a malleable material , malleability property


2) Tensile : steal rope which used to pull a car , Compression : the car cylinders that is connected , Shear : cutting the material

1. because it is not malleable and it is hard to bend.

2.tensile : steel rope
compression : Connecting Rod
shear: cutting metal sheet


3-elastic: rubber
plastic: steel,lead
brittle: concreteti

1- Cast iron is a Brittle material
which have low malleability,
The material malleability.

2- Tensile - Pulling a car with a rubber.
Compression - Car Cylinder.
Shear - cunning wood or plastic.

3- ealistic : Rubber
Plastic : steel and Lead
Brittle: Concretes
