The following data are collected during a tensile test in which the starting gage length = 125.0 mm and the cross- sectional area = 62.5 mm2:
Load (N) 0 17,793 23,042 27,579 28,913 27,578 20,462
Length (mm) 0 125.23 131.25 140.05 147.01 153.00 160.10
The maximum load is 28,913 N and the final data point occurred immediately prior to failure.
(a) Determine yield strength Y,
A.Y = 210.31 MPa.
B.Y = 230.46 MPa.
C.Y = 310.27 MPa
D.Y = 330.54 MPa.
(b)Determine modulus of elasticity E,
a.E =168,625 MPa.
b.E =175,43 MPa
c.E =199,33 MPa.
d.E =210,75 MPa
(c) Determine tensile strength TS.
a.TS = 88.36 MPa.
b.TS = 234.72 MPa
c.TS = 426.6 MPa
d.TS = 689.21 MPa.

不会呀～～～看不明白啥意思...关注～
这是道有关拉伸试验的物理题，忘光了都，呵呵
有关拉伸啊，我才初二，还没学呢。
