Applying the compressive load until ________.
Give this one a try later!
, The load indicator shows that the load is decreasing steadily. The Stress
rate decreases due to cracking in the specimen. The specimen displays a
well- defined fracture pattern. The user is certain that the ultimate capacity
has been attained when a type 5 or type 6 fracture has occurred. The load
has dropped to a value that is less than 95% of the peak load when using a
testing machine with an automatic shut off.
As the ultimate load is being approached and the stress rate decreases due to
cracking in the specimen, the rate of movement shall be decreased to avoid a
premature break. True or False?
Give this one a try later!
False.
A specimen with a diameter of 6 inches and a height of 6 inches shall have its
compressive strength adjusted by multiplying it by a correction factor of ___________?
Give this one a try later!
0.93
The average compressive strength shall be calculated to the nearest _________ psi.
