  • 2. 

    The piston and crankshaft are connected by the ---

    • Serpentine belt

    • Connecting rod

    • Piston arm

    Correct Answer
    A. Connecting rod
    Explanation
    The piston and crankshaft are connected by the connecting rod. The connecting rod is a crucial component in an internal combustion engine as it transfers the linear motion of the piston into rotational motion of the crankshaft. It connects the piston to the crankshaft journal, allowing the reciprocating motion of the piston to be converted into rotary motion. This connection is essential for the engine's operation, as it enables the conversion of the up-and-down motion of the piston into the rotational motion needed to drive the vehicle.

    The function of the throw is to rotate the ---

    • Crankshaft

    • Wheels

    • Tracks

    Correct Answer
    A. Crankshaft
    Explanation
    The function of the throw is to rotate the crankshaft. The throw is a part of the crankshaft that connects to the connecting rod. As the piston moves up and down, the connecting rod moves the throw, causing the crankshaft to rotate. This rotation is essential for converting the reciprocating motion of the piston into the rotational motion needed to power the vehicle. The crankshaft then transfers this rotational motion to other components, such as the wheels or the tracks, depending on the type of vehicle.

  • 4. 

    The motion an engine creates is transferred to a vehicle's wheels or tracks by means of a ---

    • Crankshaft

    • Connecting rod

    • Axle

    Correct Answer
    A. Crankshaft
    Explanation
    The motion an engine creates is transferred to a vehicle's wheels or tracks by means of a crankshaft. A crankshaft is a mechanical component that converts the reciprocating motion of the engine's pistons into rotational motion. It is connected to the pistons through connecting rods, and as the pistons move up and down, the crankshaft rotates. This rotational motion is then transmitted to the wheels or tracks of the vehicle through a system of gears and axles, allowing the vehicle to move forward or backward.

  • 5. 

    The offset section of the crankshaft that scribes a circle as the shaft rotates is called a ---

    • Pin

    • Rod

    • Throw

    Correct Answer
    A. Throw
    Explanation
    The offset section of the crankshaft that scribes a circle as the shaft rotates is called a throw. The throw is responsible for converting the linear motion of the piston into the rotational motion of the crankshaft. It is usually offset from the centerline of the crankshaft, creating an eccentric motion that allows for the smooth operation of the engine.
