🔍 Key Concepts

• Look closely at where label U is pointing in relation to the crankshaft and its rotation center. • Think about the purpose of a counterweight on a rotating shaft versus the purpose of a bearing support or frame member. • Consider which of the options is a realistic diesel engine component name and which sound more like distractors.

💭 Think About

• Is component U attached to the rotating part of the crankshaft, or is it part of the stationary engine structure? How does that affect which choices can be correct? • If the part at U moves with the crank throw, what would its main job be in terms of forces and balance? • If the part at U were a bearing support, what would you expect to see surrounding the crankshaft journal instead?

✅ Before You Answer

• Verify whether U is on the crank web opposite the crankpin (where the connecting rod is attached) or built into the engine frame/base. • Check if the name you choose is an actual, commonly used diesel engine term; be skeptical of terms like frequency tuner. • Confirm whether the function of the part at U is to carry the crankshaft in a fixed position or to balance rotating/reciprocating masses.
