The connecting rod of an internal combustion engine is subjected to
Options:
(A) compression only
(B) tension only
(C) both compression and tension
(D) torsion only
Official Answer Key:
C
Step-by-Step Solution & Explanation
During the power stroke, high gas pressure on the piston pushes the connecting rod, subjecting it primarily to compressive load. During other parts of the cycle (e.g. the exhaust/intake strokes at high engine speed, and due to reciprocating inertia forces of the piston reversing direction), the rod experiences tensile load as it pulls the piston back. Hence the connecting rod is subjected to both compression and tension over one complete cycle, making (C) correct; (A), (B) and (D) each capture only part of the actual loading condition.
