Question 4(a) A 75 mm diameter solid circular shaft rotating at 800 rpm transmits 400 kW and, inaddition, carries a tensile axial load force of 140 kN. The shaft material has a tensile yieldstrength of 110 MPa. Determine if the shaft will fail based on:(i) The maximum shear stress theory(ii) The maximum distortion energy theory(b) The state of stress at a critical point in a gray cast iron component is as follows:x = 0Oy=-180 MPaTxy = 200 MPaDetermine if failure will occur at the point according to: (i) the maximum normal stresstheory, and (ii) Mohr's failure criterion.For the cast iron the ultimate tensile strength is 290 MPa and the ultimate compressivestrength is 650 MPa.

A tensile-testing apparatus is to be constructed that must withstand a maximum load of 293516 N. The design calls for two cylindrical support posts, each of which is to support half of the maximum load. Furthermore, plain-carbon(1045) steel ground and polished shafting rounds are to be used; the minimum yield and tensile strengths of this alloy are 343 MPa and 565 MPa(82,000 psi), respectively. Specify a suitable diameter in mm for these support posts. Assume safety level is 2.3. Round your answer to 2 significant figures.
