Q3(c) A tensile-testing apparatus is to be constructed that must withstand a maximum load of 110,000N. The design calls for two cylindrical support posts, each of which is to support half of the maximum load. Furthermore, cast iron round bars are to be used; the minimum yield and tensile strengths of this alloy are 310MPa and 565MPa respectively. Assuming a safety factor of N=5 specify a suitable diameter for these support posts. (14=4)
