a) A thick steel plate of total area 840 cm2 (both sides) is exposed to air near the ocean. After 1 year it was found to have lost 502 g in weight due to corrosion. What is the rate corrosion, or corrosion penetration rate CPR, for the material in this environment? Density of steel = 7.9 g/cm3 [8 marks]
b) What type of corrosion is this? [2 marks]
c) Provide two strategies (there are more than two of course, but just choose two) for dealing with this type of corrosion [2 marks]
d Briefly summarise the pros and cons of each strategy as they might apply to a children’s playground at a seaside beach front [8 marks].

In 2010, OSHA allowed the federal alternative work procedures to expire and redefined residential construction. Currently all workers must adhere to the standard. Do you agree with this? Take a position. In addition, what is different about residential construction vs. commercial construction - in your mind and in the regulations?

Find the amount of reinforcement required. The cover thickness is
40mm, and the stirrup rebar is D10.
Design. Compressed reinforcing bars do not have to be yielded, and
the size of the section can only be increased if design is not
possible under the given conditions.
b = 310 mm, h = 520 mm, f ck = 29 MPa, f y = 520 MPa, using tensile and compressed rebar D22
