Torsional stiffness measures the amount of torque a rotating shaft can handle in a mechanical system. It is critical to understand the stress a shaft can withstand. Torsional stiffness and bending stiffness are measured in pounds per inch or newtons per meter. The rate of torsional stiffness is highest along the taut outer layer and […]
Torsional vibration in rotating systems can cause damage and failure. Parts designed to spin with constant speed or change speed are susceptible to torsional fatigue. Ductile materials with increased fracture toughness are used to construct rotating shafts, but cracks can still occur from surface defects or rolling joints. Torsional vibrations can cause random vibrations that […]
