Absolutely! Let’s break down each question step by step: --- ## The Flywheel ### **64. The flywheel is attached to the end of the ______.** - **Explanation:** The flywheel is a heavy rotating disk that stores rotational energy in engines. It is **attached to the end of the crankshaft**. The crankshaft is what translates the up-and-down motion of the pistons into rotational motion. - **Answer:** crankshaft --- ### **65. The flywheel is caused to spin by the ______ stroke and will continue to spin because it is heavy.** - **Explanation:** During the engine cycle, the power stroke is when the combustion of fuel pushes the piston down, causing the crankshaft (and flywheel) to spin. - **Answer:** power --- ### **66. When the crankshaft is coasting, it cannot slow down as quickly because the flywheel ______ keeps it spinning.** - **Options:** (A) velocity (B) compression (C) power (D) camshaft (E) crankshaft - **Explanation:** The flywheel resists changes in speed due to its **momentum** (also called "rotational inertia"). However, from the options, the most correct answer is **velocity** (A), as the flywheel’s velocity (or momentum) keeps it spinning. - **Answer:** (A) velocity --- ### **67. Identify the indicated parts in the drawing below.** You have a labeled diagram with two parts: (A) and (B). #### **How to identify:** - **(A):** The part at the end, which is the disk-like component, is the **flywheel**. - **(B):** The part which looks like a bent shaft is the **crankshaft**. --- ### **Summary Table** | Q# | Question Summary | Answer | |----|--------------------------------------------------------|----------------| | 64 | Attached to the end of the... | crankshaft | | 65 | Caused to spin by the...stroke | power | | 66 | Flywheel ____ keeps it spinning | (A) velocity | | 67 | (A) _____, (B) _____ (Refer to diagram) | (A) flywheel | | | | (B) crankshaft | --- ### **Visual Reference**  *Alt text: Illustration of a crankshaft and flywheel.
