Solution: The tool employed to measure the shaft runout is the Dual gauge . Option A: Feeler gauge A feeler gauge is used to measure the gap width or clearance between two objects. It's not specifically used to measure shaft runout. Option B: Dual gauge A dual gauge, also known as a dial gauge or dial indicator, is commonly used to measure the runout or concentricity of a shaft. It provides accurate readings of any lateral movement or deviation from the true center of rotation. Option C: Micrometer A micrometer is a precision instrument used for measuring very small distances, typically with high accuracy. It's not the primary tool for measuring shaft runout. Option D: Caliper A caliper is a measuring tool used to measure the distance between two opposing sides of an object. It's not typically used for measuring shaft runout. So, the correct tool for measuring shaft runout is Option B: Dual gauge .

Solution: In a typical 4-cylinder car engine, the number of main bearings is usually Option C: 4 . Main bearings are important components in an engine that support and allow the crankshaft to rotate smoothly. The main bearings are typically located at various points along the crankshaft to provide stability and reduce friction as the engine operates.

Solution: The correct answer is option C. Better weight distribution . In commercial vehicle layouts, the positioning of the engine forward, rear, or under the floor is mainly done to achieve better weight distribution. Weight distribution plays a crucial role in the overall performance and stability of a commercial vehicle. When the engine is located forward, it helps distribute the weight more evenly between the front and rear axles. This improves the balance of the vehicle and enhances its handling and stability, especially during cornering and braking. Alternatively, in some commercial vehicles, the engine may be located at the rear or under the floor. This configuration also helps in achieving better weight distribution by placing a significant portion of the vehicle's weight over the rear or central axles. This can provide better traction, especially in vehicles designed for off-road or heavy-duty applications. The other options mentioned in the question, such as better utilization of space, increase fuel economy, and reduce the weight of the chassis, are also important considerations in commercial vehicle design but may not be the primary reasons for determining the engine location. Hence, the correct answer is option C. Better weight distribution .

Solution: The push rod is an essential component in an internal combustion engine, especially in overhead valve (OHV) engines . It plays a crucial role in the valve actuation mechanism . Function of Push Rod: - The push rod transmits motion from the tappet (or lifter) to the rocker arm . - It helps in opening and closing the engine valves by transferring the camshaft motion. - It ensures proper valve timing and smooth engine operation. Analysis of Options: - Option A: Valve and valve spring → Incorrect , as the push rod is not directly connected to the valve spring. - Option B: Valve and rocker ram → Incorrect , because the push rod is positioned between the tappet and rocker arm , not the valve. - Option C: Tappet and rocker ram → Correct , as the push rod connects the tappet (lifter) to the rocker arm . - Option D: None of these → Incorrect , as Option C provides the correct answer. Conclusion: The correct answer is Option C: Tappet and rocker ram , as the push rod transmits motion between these two components in an engine's valve mechanism.

Solution: A commercial vehicle with two steered axles and two driving axles is called an 8 × 4 vehicle. In the 8 × 4 configuration, the first number (8) represents the total number of wheels, and the second number (4) tells us how many of those wheels are powered by the engine (driven wheels). So, in this case, the vehicle has 8 wheels in total, with 4 of them being driven by the engine (helping the vehicle move), and the other 4 are used for steering (helping to turn the vehicle). Why the other options are incorrect: Option A: 4 × 2 means the vehicle has 4 wheels, with 2 of them being driven, and the other 2 being non-driven. This is not what we’re talking about here. Option B: 2 × 4 means 2 wheels are driven and 4 are steered, which doesn’t match the description. Option D: 4 × 8 means the vehicle has 4 wheels being driven and 8 steered, which is also incorrect for this scenario. Therefore, the correct answer is Option C: 8 × 4.

Solution: In the context of automobile engineering, a "Damper" is also known as a Shock absorber . The primary function of a shock absorber in a vehicle is to dampen or absorb the shocks and vibrations caused by road irregularities, providing a smoother and more comfortable ride. It helps in maintaining contact between the tires and the road surface, improving stability and handling. Option B, "Torsion bar," Option C, "Spring," and Option D, "Radius rod," are different components in an automobile suspension system and serve different purposes. None of them is synonymous with a damper or shock absorber. Therefore, the correct term for a damper in an automobile context is Shock absorber .
