I appeared for an interview in Mar 2017.
The bench height for an open-cast mine is determined based on factors such as the type of material being mined, equipment used, safety considerations, and economic factors.
Bench height refers to the vertical distance between each level or bench in an open-cast mine.
It is determined by considering the type of material being mined. For example, softer materials may require smaller bench heights to prevent slope instabili...

Iron carbide diagram and basics of metals, non-metals, and alloys.
Iron carbide diagram shows the phases of iron and carbon at different temperatures and compositions.
Metals are elements that are typically shiny, malleable, and good conductors of heat and electricity.
Non-metals are elements that are typically dull, brittle, and poor conductors of heat and electricity.
Alloys are mixtures of two or more metals or a metal ...

Different types of gears include spur gears, helical gears, bevel gears, worm gears, and rack and pinion gears.
Spur gears have straight teeth and are the most common type of gear.
Helical gears have angled teeth for smoother operation but produce axial thrust.
Bevel gears have cone-shaped teeth and are used to change the direction of rotation.
Worm gears have a screw-like appearance and are used for high reduction ratios.

Critical velocity is the minimum velocity needed for an object to overcome a specific force or resistance.
Critical velocity varies depending on the force or resistance being overcome
It is often used in fluid dynamics to determine the speed at which a fluid flow transitions from laminar to turbulent
For example, in aerodynamics, critical velocity is the speed at which an aircraft's lift equals its weight, allowing it to
Pitting in metal structures refers to localized corrosion that creates small holes or cavities on the surface.
Pitting corrosion occurs when a small area on the metal surface becomes anodic, while the surrounding area becomes cathodic.
It is often caused by exposure to corrosive environments, such as saltwater or acidic solutions.
Pitting can lead to structural weakness and eventual failure if not addressed.
Examples of pi...
