An ASTM cast iron, grade 30, has ultimate strength at tension Sut = 406 MPa, and at compression Suc = 996 MPa. it carries static loading resulting in the following principle stress σA = 138 MPa , σB = -241 MPa. Choose the appropriate failure theory and estimate the factor of safety.
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.
What is the safety factor against yielding of a 4140 steel shaft, 2.1 in OD, 0.49 inch wall thickness, quenched and tempered at 1000°F, subject to a torsion of 10876 in·lbf and a compressive load of 14292 lbf? (Use Shigley for material properties, and the most accurate failure theory appropriate to the material.)
A bracket is under a loading condition shown below. It's made from a steel with yield strength (Sy) of 42 ksi and ultimate tensile strength (Sut) of 76 ksi. The diameter is 0.42 in and b = 1.75 in, with the load P fluctuate between 15 lbs (tension) and -5 lbs (compression). Using the modified Goodman or Gerber criterion, determine the fatigue factor of safety based on infinite life. If infinite life is not predicted, estimate the number of cycles to failure. Also check for yielding.
