🔍 Key Concepts

• Force path in a piston–connecting rod–crankshaft assembly (where does combustion force act first?) • Difference between reciprocating parts (moving back and forth) and rotating parts (spinning) in an engine • Function and location of wrist pin, crankpin, and crankshaft journal bearings

💭 Think About

• Start at the top of the engine: when combustion happens in the cylinder, which part touches the piston crown directly, and what part connects that to the crankshaft? • Which bearing is located at the joint between the piston and the connecting rod, and which bearings are further down the load path, closer to the crankshaft and shaft line? • Think about the phrase "first bearing" — at what joint does the combustion force first need a bearing surface in order to be transmitted into the rotating parts?

✅ Before You Answer

• Identify the sequence of parts from piston to crankshaft: piston → pin → connecting rod → crankpin → crankshaft journal • Confirm which option is the bearing at the piston–connecting rod connection, not at the crankshaft • Eliminate any bearing whose main purpose is to carry axial thrust from the propeller rather than direct piston combustion load
