Answer:
The length of the specimen after the load is released is 11.67 cm
Explanation:
Given;
yield stress, Y = 350 MPa
ultimate tensile stress, T = 300 MPa
Elongation factor, e = yield stress, Y / ultimate tensile stress, T
Elongation factor, e = 350 Mpa / 300 Mpa
Elongation factor, e = 1.1667
New length of the specimen = 1.1667 x 10 cm = 11.67 cm
Therefore, when the load is released from 10 cm long tensile specimen, the length of the specimen becomes 11.67 cm
