Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A steel shaft, with a shear modulus of 80 GPa, a polar moment of inertia of 0.005 m^4, a moment of inertia of 0.02 kg·m^2, and a length of 1.5 m, calculate the natural torsional frequency.

💡 Hint: Make sure to convert units where necessary.

Challenge 2 Hard

Evaluate how unmitigated torsional vibrations in a crankshaft could lead to engine failure, and discuss potential design changes to mitigate these issues.

💡 Hint: Think about what engineering solutions would reduce vibrations in practical systems.
