问道拉伸实验的题~~
A tensile test uses a test specimen that has a gage length of 50 mm and an area = 200 mm2. During the test the specimen yields under a load of 98,000 N. The corresponding gage length = 50.23 mm. This is the 0.2 percent yield point. The maximum load = 168,000 N is reached at a gage length = 64.2 mm.
(a) Determine yield strength Y,
450 MPa
468 MPa
490 MPa
520 MPa
(b) Determine modulus of elasticity E
188.5 x 10^3 MPa
124.8 x 10^2 MPa
1885.0 x 10^3 MPa
1248.0 x 10^2 MPa
