Question

5. A stepped shaft ACB having solid circular cross sections with two different diameters is held against rotation at the ends (see figure). (20 pts) a. If the allowable shear stress in the shaft is 43 MPa, what is the maximum torque $(T_0)_{max}$ that may be applied at section C? (12 pts) b. Find $(T_0)_{max}$ if the maximum angle of twist is limited to 1.85°. Let $G = 28 \text{ GPa}$. (8 pts) 20 mm 25 mm A C B $T_0$ 225 mm 450 mm

Step 1

- Allowable shear stress, $ \tau_{\text{allow}} = 43 \, \text{MPa} $ - Diameter of section AC, $ d_1 = 20 \, \text{mm} $ - Diameter of section CB, $ d_2 = 25 \, \text{mm} $ - Length of section AC, $ L_1 = 225 \, \text{mm} $ - Length of section CB, \( L_2 = Show more…
