Question

A cylindrical specimen of a brass alloy 8.3 mm (0.33 in.) in diameter and 76.7 mm (3.02 in.) long is pulled in tension with a force of 7360 N (1655 lbf); the force is subsequently released.
(a) Compute the final length of the specimen at this time. The tensile stress-strain behavior for this alloy is shown in Animated Figure 7.12.
(b) Compute the final specimen length when the load is increased to 20300 N (4563 lbf) and then released.

Answer 1

Here is what I solved before, please modify the figures as per your question. Please let me know if you have further questions. Ifthis helps then kindly rate 5-stars.

A cylindrical specimen of a brass alloy 9.1 mm (0.36 in.) in diameter and 93.0 mm (3.66 in.) long is pulled in tension with a force of 3680 N (827.3 lbf); the force is subsequently released.
(a) Compute the final length of the specimen at this time. The tensile stress-strain behavior for this alloy is shown in Animated Figure 6.12.
(b) Compute the final specimen length when the load is increased to 24200 N (5440 lbf) and then released.

What is the final length, in mm, of the specimen after the 24200 N is released?
