Answer all the questions.
Do research from internet, newspaper, articles to answer the questions
For the identical answer, a “0” will be assigned
Figure 1 below depicts an example of a car frame and body structure.
Determine the materials (2) that are commonly used in each part of the body
structure.(5 Marks)
Explain the ultimate tensile strength, young modulus, toughness, and strength of
each of the materials you chose to use in your justification. It is recommended that
you support the answer with examples of the graph properties of the materials.

Flexural modulus refers to a material’s ability to resist deformation in bending
while tensile modulus (Young’s Modulus) refers to a material’s ability to resist
deformation when in tension or compression.
Explain the differences between carbon fibre, Kevlar, fibreglass, and hybrid
textiles.
(6 marks)
Discuss both the advantages and the disadvantages of these materials, as well as
why they are employed to make car parts rather than aluminium.
(7 marks)
Draw and describe the Young’s modulus graph of carbon fibre, Kevlar, fibreglass,
and hybrid textiles.
