1) State five factors that must be considered when choosing a material. Discuss the importance to the engineer of each of these factors.
2) An engineer is planning to design a small boat: he has the choice of aluminium or steel. From the information below make an informed decision, with justifications, on which material should be used
Aluminium
Steel
Weight
2.65 tonnes/m3
7.86 tonnes/m3
Yield strength
275 MPa
205 MPa
UTS
310 MPa
345 MPa
corrosion
Excellent
Poor
You should comment on each of the above material characteristics for each material before making your choice.
3) When designing a product this must be systematic. Briefly discuss what stages need to be considered when designing a product from 'scratch'.
4)
a) List what factors you would need to consider for a systematic approach to the design of a new product.
b) Comment on the properties that a operational and saleable product must have e.g a new car.
