Question 13 1 pts #26-A. Determine the allowable bending stress number for through-hardened, grade 1 steel with a hardness of 200 HB? (+/- .1 KSI) Question 14 1 pts #26-A. Determine the allowable contact stress number for through-hardened, grade 1 steel with a hardness of 200 HB? (+/-.1 KSI) Question 15 #27. If the design of a steel gear indicates that an allowable bending stress number of 36 KSI is needed, specify a suitable hardness level for grade 2 steel? (+/- 5 BHN) Question 16 #28. What level of hardness can be expected for gear teeth that are case-hardened by carburizing? (Specify a number in the range of the HRC levels) 1 pts 1 pts
