![]() ![]() I thought someone had asked this before and I see that was about this time last year, but the OP never came back. 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 thick does the plate have to be if granite fails in tension at 20 MPa Assume 2700 kg m3.Hello, I must resolve this problem ('Geodynamics'), but I dont understand the methodology to obtain the answer (0.4. How this does the plate have to be if granite fails in tension at 20 MPa? Assume density is 2700 kg m^3. Problem 3.14 A granite plate freely supported at its ends spans a gorge 20 m wide. ![]()
