Phoenix Interview Questions and Answers

The flywheel is a mechanical device that stores rotational energy and helps in maintaining the engine's speed and stability.

• The flywheel is connected to the crankshaft of the engine and stores excess energy during the power stroke.

• During the compression stroke, the stored energy in the flywheel helps in maintaining the engine's momentum and smooth operation.

• The flywheel also acts as a rotational inertia, reducing speed fluctuations and providing a consistent power output.

Heat is transferred in convection through the movement of a fluid medium.

• Convection is a mode of heat transfer that occurs in fluids (liquids or gases).

• Heat is transferred through the movement of the fluid particles.

• Hot fluid rises, creating a convection current, while cold fluid sinks.

• Examples of convection include boiling water, wind, and ocean currents.

Three point linkage is a mechanism used in tractors to connect and control implements, providing stability and flexibility.

• Three point linkage is a system of three hydraulic arms that connect the tractor to an implement.

• It allows the implement to be raised, lowered, and tilted as needed.

• The three points of connection provide stability and prevent the implement from swaying or tipping.

• The top link controls the vertical movement, while the lower links control the lateral moveme...read more

Rear tires are big in tractors to provide better traction, stability, and weight distribution.

• Big rear tires offer increased traction, allowing tractors to navigate through rough terrains and pull heavy loads.

• The larger surface area of the rear tires distributes the weight of the tractor more evenly, reducing soil compaction and preventing sinking in soft ground.

• Bigger tires also enhance stability, preventing the tractor from tipping over during sharp turns or when carrying h...read more

Wet brakes are more efficient than dry brakes due to better heat dissipation and reduced wear and tear.

• Wet brakes have a cooling effect due to the presence of water, which helps in dissipating heat generated during braking.

• Wet brakes also have reduced wear and tear as the water acts as a lubricant, reducing friction between the brake pads and the rotor.

• Dry brakes, on the other hand, generate more heat and can cause brake fade, reducing their efficiency.

• Examples of wet brakes ...read more

1st angle and 3rd angle projection are two methods used in technical drawing to represent three-dimensional objects on a two-dimensional surface.

• 1st angle projection is commonly used in Europe and Asia, while 3rd angle projection is commonly used in North America.

• In 1st angle projection, the object is imagined to be in the first quadrant and the views are projected onto the planes surrounding the object.

• In 3rd angle projection, the object is imagined to be in the third quadra...read more

Tires are black in color due to the presence of carbon black.

• Carbon black is added to the rubber during the manufacturing process to improve its strength and durability.

• It also helps to protect the tire from UV rays and heat.

• Tires without carbon black would be more susceptible to cracking and wearing out quickly.

• Other colors of tires are available, but they are less common and often used for aesthetic purposes only.

Compression ratio is the ratio of the volume of the combustion chamber from its largest capacity to its smallest capacity.

• Compression ratio is an important factor in determining the efficiency and power output of an engine.

• In SI engines, the compression ratio is typically between 8:1 to 12:1.

• In CI engines, the compression ratio is typically between 14:1 to 25:1.

• Higher compression ratios lead to higher thermal efficiency and power output, but also require higher octane fuel in...read more
