    Hi. Im a student from South Africa. Currently studying Civil engineering. Came here for a lot of questions and this seems to be the place where great minds are.

    P.S. NO, I don't have a pet Lion or Cheetah. :)

    Thank you.

    Quick question where it is 1:52am on my side of the planet....

    Where can I ask a question regarding "homework" related to civil engineering?
    There are no examples in the study material. I am doing this course as part of distance-learning so there are also no one I could ask for advice. I have been through 3 books that I received and there is nothing like this in the books.

    Question are as follows:
    A steel bar, area 625mm2, is embedded in a block of concrete 100mm x 100mm. The length of both the steel bar and concrete block is 300mm. Assuming a value of 210kN/mm2 for Young's Modulus for the steel and 14kN/mm2 for the concrete, determine the load carried by the steel,and the load carried by the concrete, if the combined section is subject to a compressive load of 5kN. Assume that there is no slip between the steel and concrete(i.e. the strain in both materials is equal) and that the load is applied over the entire cross-section.

    You will find a polite attitude will encourage people to help you. :smile: I don't know anything about civil engineering unfortunately.
