5. At least 30 __ of crosshead travel or more for high elongation materials.
a) cm
b) inches
c) mm
d) m
View Answer
Explanation: At least 30 inches of crosshead travel or more for high elongation materials.
6. Ring tensile strength is __________
a) Proportional to time
b) Inversely proportional to time
c) Inversely proportional to hydrostatic pressure
d) Inversely proportional to average diameter of ring
View Answer
Explanation: fr =PD/2t where P= hydrostatic pressure, D= average diameter of ring, t= time.
7. The tensile properties of a low-pressure plasma-deposited nickel-base superalloy from ____________
a) 25 to 100° C
b) 250 to 1010° C
c) 25 to 1010° C
d) 100 to 250° C
View Answer
