Hi guys, So I'm at Uni studying Building Surveying but my maths is ok, not great and I 'm stuck on this question in my course work:

1. a) The external skin of your domestic building is likely to be brickwork. Assuming that this is the case, and knowing that the crushing strength of Facing Bricks is 15N/mm2, show by calculations that those on the bottom of the external skin can take to load from a 6.0m high wall and from two floors and a roof. The weight of a half brick skin of brickwork is 225kg/m2 of elevation area, plus the weight from each floor is 5kN and from the roof 2kN. Assume each brick supports a column of brickwork above 225mm wide (therefore ignoring openings for windows and doors).

It's asking me to calculate the stress in one brick and prove whether or not it can take the load

Do let me know if you need more information.

Many thanks
