The lower end of the piston rod, shown in the illustration, is fitted into the_______________. Illustration MO-0003
AI Explanation
The correct answer is B) crosshead.
The lower end of the piston rod is fitted into the crosshead, which is a mechanical component that connects the piston rod to the crankshaft. The crosshead acts as an intermediary between the reciprocating motion of the piston and the rotational motion of the crankshaft, helping to transmit the power from the piston to the crankshaft.
The other options are incorrect because: A) the crankpin is the journal on the crankshaft that the connecting rod is attached to, not the piston rod; C) the piston pin connects the piston to the connecting rod, not the piston rod; and D) the crosshead guide is a stationary component that the crosshead slides along, not the component the piston rod is connected to.
