A large water tank that has a capacity to carry 20,000 liters is to be supported by four cylindrical posts. These four support posts are made of plain carbon (1045) steels with the yield and tensile strengths of 310 MPa and 565 MPa, respectively. Determine the minimum required diameter of the post assuming a factor of safety of 5.

12-10. A metal bar is being compressed along the x,-axis between two rigid walls such that e3 = 0 and σ2, = 0. This process causes an axial stress σ1 and no shearstresses. Determine the apparent yield value of σ1, if the material in a conventional compression test exhibits a yield strength σyp and Poisson's ratio v. Assume that the material is governed by the von Mises yield condition. Find an alternative expression if the Tresca condition is postulated.
The center post B of the assembly has an original length of 122 mm, whereas posts A and C have a length of 126 mm.
