This is homework help so show us how you get on with this information and see if more help is required.ĭon't just pick equations at random from the book, have a good reason for choosing. This stress can be related to the horizontal tension and compression (shearing stress) distribution at that section by the usual 'bending equation' which will give you a value for the half-depth. You can thus calculate the maximum bending stress in the middle. That will give you a volume and therefore a uniformly distributed load on each strip. Since no further information is provided (about the plate dimensions or tother loadings) I am further going to guess that you are meant to analyse the plate as a series of 1metre wide strips. How thick this does the plate have to be if granite fails in tension at 20 MPa? Assume density is 2700 kg m^3. I am going to guess (I don't know the book) that your question should read ![]() How this does the plate have to be if granite fails in tension at 20 MPa? Assume density is 2700 kg m^3.
