← ScienceWhich consequence results when a reciprocating engine encounters hydraulic lock?
A)Connecting rod experiences catastrophic bending failure✓
B)Crankshaft seals undergo rapid delamination
C)Piston rings quickly lose elastic tension
D)Valve springs exhibit accelerated fatigue propagation
💡 Explanation
Hydraulic lock occurs when incompressible fluid enters a cylinder; because the liquid cannot compress during the compression stroke, excessive stress damages the connecting rod via plastic deformation, therefore bending failure results, rather than damage to seals or rings, which would occur with excessive temperature instead.
