← TechnologyWhich outcome occurs when extreme cyclic loading causes a hydraulic actuator's piston rod's surface finish falters?
A)Accelerated fatigue crack propagation✓
B)Decreased bulk modulus of elasticity
C)Increased fluid film cavitation
D)Reduced actuator thermal expansion
💡 Explanation
The increased surface roughness creates stress concentrators where minute cyclic loading-induced crack initiates, leading to fatigue crack propagation in a fracture mechanism. Therefore, fatigue occurs, rather than bulk modulus loss, because rough surface enhances crack growth under cyclical load.
