Question

Bring the loading block in contact with the surface of the specimen at the third points and apply eight force between blank and blank of the estimated ultimate force.

a. One-third and one-half
b. One-fourth and three-fourths
c. One-fifth and four-fifths
d. One-sixth and five-sixths

Answer 1

The answer involves a procedure in materials testing where the load should be applied between one-third and one-half of the estimated ultimate force of a test specimen.

Step-by-step explanation:

The question seems to be about the procedure for applying a load to a test specimen in the context of materials testing, more specifically, perhaps a fracture toughness test or a tensile test. The correct option for applying the force between a range relative to the estimated ultimate force of the specimen is one-third and one-half. This suggests the loading should begin at a moderate level, not too low to be ineffective in testing the specimen's response, yet not too high to potentially cause an immediate fracture or yielding.
