Chapter 5, Reserve Problem 026 A solid aluminum [E = 70 GPa; a = 22.5 x 106/°C] rod (1) is connected to a solid bronze [E = 100 GPa; a = 16.9 x 106joc] rod (2)vat flange B as shown. Aluminum rod (1) has an outside diameter of 58 mm, and bronze rod (2) has an outside diameter of 110 mm. The bars are unstressed when the structure is assembled at 30°C. After the 300-kN load is applied to flange B, the temperature increases to 45°C.

Q-2      The rotating shaft running at n = 900 rpm, shown in the figure below, is machined from AISI 1045 CD steel. It is subjected to a force of F = 10.1 kN. The shaft is experiencing an operating temperature of 35 oC. With the specified loading and for a reliability of 99.9 %, a) Determine the minimum factor of safety for fatigue based on infinite life*.         b)  Determine the maximum safe load (Fmax) that can be applied for a factor of safety of 1.5 and a design life of 5x105 cycles, all other input values remaining the same.  c)  Determine factor of safety against yielding.     *Free-body, shear-force and bending moment diagrams are required.
