A part made from annealed AISI 1018 steel undergoes a 20 percent cold-work operation. Determine the true strain of the material due to cold-working. Also specify what happens to the material due to cold-working. The yield strength before cold-work operation is 32 32 Correct kpsi. The yield strength after cold-work operation is 61.8 61.8 Correct kpsi. The percentage increase in yield strength is 93 93 Correct percent. The percentage increase in ultimate strength is 25 25 Correct percent. The true strain is 0.25 0.25 Incorrect .

explanation:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only
