🔍 Key Concepts

• Fork and blade connecting rod arrangement in V-type diesel engines • How the fork (master) rod straddles the crankpin and the blade (articulated) rod fits between its cheeks • Distinguishing connecting rods vs. crankshaft webs/journals in a sectional drawing

💭 Think About

• First, locate the crankshaft and crankpin, then identify which labeled parts are actually connecting rods rather than bearings or webs. • Look for the rod that is split into two cheeks forming a "fork" around the crankpin, and the slimmer rod that sits between those cheeks on the same crankpin. • Check which labels point to the big-end areas versus labels that point to the crank web or counterweight; eliminate any choices that clearly identify a non-rod component.

✅ Before You Answer

• Verify which letter label points to the wide, split rod that surrounds both sides of the crankpin (fork/master rod). • Verify which numerical label points to the narrower rod sandwiched between the fork cheeks (blade/articulated rod). • Confirm that both selected labels are attached to parts that connect the pistons to the crankshaft, not to stationary structures or the crankshaft itself.
