a Describe corrosion mechanism of iron.
b Using this, explain the statement Corrosion is reverse metallurgy, c Mention common methods of corrosion prevention.
a For oil-based paints, discuss the major components and their main functions, b What are the desirable properties of an ideal paint?
a Describe 5 different types of glass, b How float glass is manufactured?
c A design studio is on 14* floor of an office tower. Its windows face south-west and a busy street. For the windows, what type of glass will you recommend and why?
In a water tank, you are floating in a boat with a big concrete block in your hand. If you drop the block in water, will the water level rise, fall or remain same? You repeat the experiment, but this time the block has many holes drilled in it. The holes extend from one surface to other surface of the block. What will happen to water level now? Logically support your answer. Make necessary assumptions.
The nest figure shows stress-strain behavior of atypical ductile material. Match points (A,B.C etc) shown in figure with the following alphabetical list of terminologies.
