Problem #1 A cylindrical rod of copper (E 110 GPa) having a yield strength of 240 MPa is to be subjected to a load of 6660 N. If the length of the rod is 380 mm, what must the diameter be to allow an elongation of 0.50 mm? A cylindrical specimen of some alloy 8 mm in diameter is stressed elastically in tension. A force of 15,700 N produces a reduction in the specimen diameter of 5 10-3 mm. Compute...
rn A specimen of copper having a rectangular cross section 15.2 mm x 19.1 mm is pulled in tension with 44,500 N force, producing only elastic deformation. Calculate the resulting strain. Round off the answer to three significant figures. Answer: 1.394e-3 A cylindrical specimen of a nickel alloy having an elastic modulus of 207 GPa and an original diameter of 10.2 mm experiences only elastic deformation when a tensile load of 8900 N is applied. Compute the maximum length of...
1. Draw a schematic stress-strain diagram for steel. Make sure you mark all the important points and regions on it. Provide a one-two sentence explanation for each point and region along the diagram. 2. A cylindrical specimen of a nickel alloy having an elastic modulus of 207 GPa (30 x 10* psi) and an original diameter of 10.2 mm (0.40 In.) will experience only elastic deformation when a tensile load of 8900 N (2000 Ibe) is applied. Compute the maximum length...

Question 1 A turning operation is carried out on aluminum. Based on the specific energy values in Table 20.2, determine material removal rate and cutting power in the operation under the following sets of cutting conditions: (a) Cutting speed 5.6 m/s, feed 0.25 mm/rev, and depth of cut 2.0 mm; and (b) cutting speed- 1.3 m/s, feed 0.75 mm/rev, and depth 4.0 mm. Question 2 Consider a turning operation performed on steel whose hardness 225 HB at a cutting speed...
