Hardness is a measure of a material's resistance to deformation or scratching.
Hardness is often measured using the Mohs scale for minerals or the Rockwell scale for metals.
Materials with higher hardness values are more resistant to wear and abrasion.
Hardness can also affect a material's machinability and ability to be shaped or formed.
Common examples of hard materials include diamond, steel, and ceramics.
Yield point is the stress at which a material begins to deform plastically.
Yield point is the point on a stress-strain curve where the material transitions from elastic to plastic deformation.
It is an important property in materials science and engineering as it indicates the maximum stress a material can withstand without permanent deformation.
Yield point is typically determined through tensile testing of materials.

Different types of loads applied on long and short steel columns
Long columns are more susceptible to buckling under compressive loads
Short columns are more susceptible to crushing under compressive loads
Long columns are more likely to experience bending under lateral loads
Short columns are more likely to experience shear under lateral loads
Examples of loads include dead load, live load, wind load, seismic load, etc.

Current affairs and technical both questions will come be ready
Questions related to electrical engineering - transformer, motor principle and types of motors.
Transformer works on the principle of electromagnetic induction to transfer electrical energy from one circuit to another.
Motor principle is based on the interaction between magnetic fields and electric currents to produce rotational motion.
Types of motors include AC motors, DC motors, stepper motors, servo motors, etc.
