"Look at Equation 3-6," Dr. Vance pointed. Leo read aloud:
"New shaft diameter: 94 mm," Leo said. The replacement shaft—94 mm solid steel—was installed by 5:30 AM. As the sun rose over the SS Resilient , Leo looked at the Chapter 3 solutions in his textbook. They weren't just answers to odd-numbered problems. They were a map of how materials behave when twisted—elastically at first, then plastically, then fatally.

Where (G) is the shear modulus of elasticity (77 GPa for steel), and (L) is the length of the shaft (2.5 m). "Look at Equation 3-6," Dr
