Two-stroke and four-stroke engines are types of internal combustion engines. Punching and blanking are metal forming processes.
Two-stroke engine: Combustion occurs in every revolution of the crankshaft. It has fewer parts and is lighter but less efficient than a four-stroke engine.
Four-stroke engine: Combustion occurs every two revolutions of the crankshaft. It has more parts and is heavier but more efficient than a tw...

Iron carbon diagram is a graphical representation of the phases of iron and carbon at different temperatures.
Shows the phases of iron and carbon at different temperatures
Helps in understanding the microstructure of steel
Consists of regions like austenite, ferrite, cementite, and pearlite
Steel is an alloy of iron and carbon, with various other elements added to enhance its properties.
Steel is primarily composed of iron and carbon, with carbon content typically ranging from 0.2% to 2.1%.
Alloying elements like manganese, chromium, nickel, and molybdenum are added to improve strength, hardness, and corrosion resistance.
Different types of steel include carbon steel, stainless steel, and tool steel, each wi
Fuel injectors in diesel engines are responsible for delivering fuel into the combustion chamber at high pressure.
Fuel injectors atomize the fuel into a fine mist for better combustion efficiency.
They are controlled by the engine's electronic control unit (ECU) to precisely regulate fuel delivery.
Common issues with fuel injectors include clogging, leaking, or failing to open/close properly.
Regular maintenance and clean...

Basic quantitative aptitude, English, and reasoning skills are essential; quick solving abilities are necessary due to the limited time available, making both speed and accuracy important factors.
Heat treatment processes involve heating and cooling metals to alter their properties.
Heat treatment processes involve heating metals to specific temperatures and then cooling them at controlled rates.
Common heat treatment processes include annealing, tempering, quenching, and normalizing.
These processes can change the hardness, strength, toughness, and other properties of metals.
For example, quenching involves rapid c...
Surface tension is the property of a liquid that allows it to resist an external force due to the cohesive nature of its molecules.
Surface tension is caused by the attraction between the molecules of a liquid, which creates a 'skin' on the surface of the liquid.
It is responsible for phenomena like capillary action, where liquids rise in narrow tubes against the force of gravity.
Surface tension can be observed in everyd...
Mass is the amount of matter in an object, while weight is the force of gravity acting on an object.
Mass is a scalar quantity and is measured in kilograms or grams.
Weight is a vector quantity and is measured in newtons.
Mass remains constant regardless of location, while weight changes depending on the gravitational pull.
For example, a person with a mass of 70 kg will have a weight of approximately 686 newtons on Earth,
Modes of heat transfer include conduction, convection, and radiation.
Conduction: Heat transfer through direct contact between particles. Example: Touching a hot stove.
Convection: Heat transfer through the movement of fluids (liquids or gases). Example: Boiling water.
Radiation: Heat transfer through electromagnetic waves. Example: Feeling the warmth of the sun.

1st angle and 3rd angle projection differ in the placement of the object and the observer in relation to the projection plane.
1st angle projection places the object in front of the projection plane, while 3rd angle projection places the object behind the projection plane.
In 1st angle projection, the observer views the object from the opposite side of the projection plane, while in 3rd angle projection, the observer vie...
