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.

Theories of failure are mathematical models used to predict the failure of materials under different loading conditions.
Theories of failure help engineers design structures that can withstand different types of loads.
Some common theories of failure include maximum shear stress theory, maximum normal stress theory, and maximum strain energy theory.
These theories are based on different assumptions about the behavior of m...
Diesel cycle is a thermodynamic cycle used in diesel engines to convert heat into work.
Air is compressed in the cylinder, causing its temperature to rise.
Fuel is injected into the cylinder, igniting due to the high temperature.
The expanding gases push the piston, converting heat into mechanical energy.
Exhaust gases are expelled from the cylinder.
Diesel cycle is more efficient than Otto cycle used in gasoline engines.
