1.) 20 pound test fishing line has a diameter of 0.017". A fish pulls with a force of 12 pounds
which does not induce yielding in the line. The elastic modulus of the line is E = 450 ksi.
a. What is the stress in the line due to the fish?
b. What is the strain in the line due to the fish?
2.) A 15.0' round aluminum rod is 0.625" in diameter. It is loaded in tension and measured to
be 15.04'. The Young's modulus is 10.0 X 106
a. What is the stress in the rod due to the load?
b. What was the load was required to stretch the rod this amount?
3.) A 15/16" diameter rod of half-hard, yellow brass (C27000 - H02) has the material
properties, E = 15.0 X 106
psi, ? = 0.33, and is loaded in compression. The bar is exactly 4 ¾" long
before loading along the long axis. What are the final dimensions of the bar while it is being loaded
with 75,000 pounds? Assume it remains entirely elastic during the loading.
4.) A round wire (E = 73 MPa, ? = 0.33) with a nominal diameter of 2.122" is loaded in tension.
When it is loaded, the diameter changes to 2.120".
a. What is the tension, in pounds, that the wire is subjected to?
b. What is the stress in the rod when this load is applied?
