Question: 4) The rotating shaft shown below carries a steady torque of 6,000,000 N-mm and a load of 30,000 N as shown. If a 30mm hole

4) The rotating shaft shown below carries a steady torque of 6,000,000 N-mm and a load of 30,000 N as shown. If a 30mm hole is drilled through the shaft near the point where the bending moment is maximum, will the shaft fail is Syp=620 MPa, Se=300 MPa and Nfs=2.0? Hint: The hole creates stress concentration
