square tensile specimen with a 2 cm x 2 cm cross section is subjected to a tensile test until fracture. what was the maximum load this sample saw during the test?

Pmax = 405KNStrain rate is defined as the change in strain with respect to the time.Strain rate = Change in strain\div change in timeThe low strain rate situation is seen in hardness test, this is a widely used technique to measure strain rate dependance of the hardness. The strain rate during the indentation test is said to be the ratio of indentation velocity to the depth of indentation. Ultimate tensile strength is defined as the maximum load acting on the cross sectional area of the part.Hence,Ultimate tensile strength = Maximum load \divCross sectional areafrom the plot we have UTS = 450MPacross sectional area of square = 30 * 30 sq.mm450 = \frac{P^{_{max}}}{900}Pmax = 450*900Therefore Pmax = 405KNyou can learn more through link below:https://brainly.com/question/13093869#SPJ4
