Crosshead function in a reciprocating steam engine: fill in the missing part correctly. The function of a crosshead is to guide the motion of the __________ and prevent it from bending, while transmitting force to the connecting rod. Choose the correct completion.

Difficulty: Easy

piston rod
connecting rod
eccentric rod
valve rod

Correct Answer: piston rod

Explanation:

ConceptThe crosshead maintains straight-line guidance of the piston rod and prevents it from bending under side thrust, while providing the joint to the connecting rod for rotary conversion at the crank.

Final Answerpiston rod
