🔍 Key Concepts

• Frame box construction of large slow-speed crosshead diesel engines (bedplate, columns, entablature) • Purpose and function of tie rods in holding the structure together • Which members are primarily in compression vs primarily in tension under firing loads

💭 Think About

• Picture the gas pressure pushing down on the piston and transmitting the load through the connecting rod and crank—what does that do to the bedplate and columns? • Ask yourself: if the top of the engine wants to "lift" away from the bottom under firing load, which part must be resisting that separation by being stretched? • Which of these listed parts is specifically designed as a long, slender member to clamp the entablature to the bedplate?

✅ Before You Answer

• Identify which components (bed plate, column, entablature) mainly carry compressive forces when the cylinder fires • Recall the stated function of tie rods in engine design from your textbooks or class notes • Verify which listed part is explicitly described as being in tension to prevent the structure from "opening" under firing loads
