Question
![An annealed-steel specimen has a 0.750 in. diameter and a 12.000 in. gage
length. Maximum load is reached at 60,000 lbs and fracture occurs at 30,000
Ibs.
For this steel, E= 360 x 10° psi.
(a) Draw a sketch of stress-strain diagram for a typical steel in tension?
(b) What is the ultimate tensile strength (UTS)?
(c) Why does fracture occur at a lower load than the maximum load?
(d) What is the elongation when a tensile stress of 30,000 psi is applied?
A 400-mm-long rod with a diameter of 4.5 mm is loaded with a 5000-N
weight. If the diameter decreases to 3.5 mm, compute the final length of the
rod.
3.
4. A steel rod 1.5 m long and 75 mm x 75 mm in cross-section is subjected to a
tensile force of 160 kN. Determine the elongation of the rod, if modulus of
elasticity for the rod material is 900 GPa.
5. A hollow cylinder 4.5 m long has an outside diameter of 80 mm and inside
diameter of 60 mm. If the cylinder is carrying a load of 75 kN, find the stress
in the cylinder. Also find the deformation of the cylinder, if the value of
modulus of elasticity for the cylinder material is 600 GPa.
