A solid aluminum [E = 76 GPa] rod (1) is connected to a solid bronze [E = 93 GPa] rod (2) at flange B
A solid aluminum [E = 76 GPa] rod (1) is connected to a solid bronze [E = 93 GPa] rod (2) at flange B, as shown. Aluminum rod (1) has an outside diameter of 31 mm and bronze rod (2) has an outside diameter of 15 mm. The norma stress in the aluminum rod must be limited to 128 MPa, and the normal stress in the bronze rod must be limited to 97 MPa. Assume L1 = 180 mm and...

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...
