A) Suppose you need to design a tension test machine capable of testing specimens that have nominal ultimate stresses as high as σu = 100 ksi . How much force must the machine be capable of generating? Assume the testing specimen has the ASTM shape shown.B) If the maximum nominal strain is ϵf = 0.7 just before the test specimen fractures and the test machine operates by moving only one grip, how far must that grip be designed to travel? The total length of the deforming part of the specimen is 3 in . The image depicts a cylindrical rod with threaded ends. The central section of the rod is smooth, and this part is highlighted with two dimensional notations:- \( d_0 = 0.5 \, \text{in.} \): This represents the diameter of the smooth middle section of the rod.- \( L_0 = 2 \, \text{in.} \): This indicates the length of the smooth middle section between the threaded ends.The threads at both ends suggest this rod may be used for fastening or joining in mechanical applications. The diagram helps illustrate these key dimensions for understanding the rod's specifications.

A) Suppose you need to design a tension test machine capable of testing specimens that have nominal ultimate stresses as high as σu = 100 ksi . How much force must the machine be capable of generating? Assume the testing specimen has the ASTM shape shown.

B) If the maximum nominal strain is ϵf = 0.7 just before the test specimen fractures and the test machine operates by moving only one grip, how far must that grip be designed to travel? The total length of the deforming part of the specimen is 3 in .

The image depicts a cylindrical rod with threaded ends. The central section of the rod is smooth, and this part is highlighted with two dimensional notations:

- \( d_0 = 0.5 \, \text{in.} \): This represents the diameter of the smooth middle section of the rod.
- \( L_0 = 2 \, \text{in.} \): This indicates the length of the smooth middle section between the threaded ends.

The threads at both ends suggest this rod may be used for fastening or joining in mechanical applications. The diagram helps illustrate these key dimensions for understanding the rod's specifications.
