고체역학 (Gere) — Torsion: Problem 3.12-4
3.12-4 The stepped shaft shown in the figure is required to transmit 600 kW of power at 400 rpm. The shaft has a full quarter-circular fillet, and the smaller diameter \( D_1 = 100 \text{ mm} \). If the allowable shear stress at the stress concentration is 100 MPa, at what diameter \( D_2 \) will this stress be reached? Is this diameter an upper or a lower limit on the value of \( D_2 \)?
