(Solved): The horizontal shaft AD is attached to a fixed base at D and is subjected to the torques TA= ...

The horizontal shaft $$AD$$ is attached to a fixed base at $$D$$ and is subjected to the torques $$T_A=260\mathrm{N}?\mathrm{m}$$ and $$T_B$$ $$=2525$$ N.m shown. A 48-mm-diameter hole has been drilled into portion CD of the shaft. Given that $$d_0=80\mathrm{mm}$$, $$d_s=30\mathrm{mm},L_{AB}=420\mathrm{mm},L_{BC}=200\mathrm{mm},L_{CD}=590\mathrm{mm}$$. Knowing that the entire shaft is made of the same material for which $$\mathrm{G}=76\mathrm{GPa}$$. Select the closest choice to your solution and ONLY TYPE THE LETTER IN THE BLANK (A, B, C, D, E): (Q1) Determine the maximum shear stress $$(\mathrm{MPa})$$ in the shaft CD. $$\begin{array}{ll}\text{ A }& 27.7\\ \text{ B }& 31.8\\ \text{ C }& 28.9\\ \text{ D }& 130.8\\ \text{ E }& 3\end{array}$$ Answer for (Q1)Blank 1 (Q2) Determine the maximum shear stress (MPa) in the whole shaft AD. $$\begin{array}{ll}\text{ A }& 130.8\\ \text{ B }& 27.7\\ \text{ C }& 49\\ \text{ D }& 104.6\\ \text{ E }& 98.1\end{array}$$ Answer for (Q2)Blank 2 (Q3) Determine the angle of twist (degrees) at end $$A$$. $$\begin{array}{cc}\text{ A }& 0.46\\ \text{ B }& 1.49\\ \text{ C }& 0.35\\ \text{ D }& 1.14\\ \text{ E }& 1.95\end{array}$$ Answer for (Q3)Blank 3 (Q4) Determine the angle of twist (degrees) at end B. $$\begin{array}{cc}\text{ A }& 1.49\\ \text{ B }& 0.35\\ \text{ C }& 1.95\\ \text{ D }& 1.14\\ \text{ E }& 0.46\end{array}$$ Answer for (Q4)Blank 4
