The weight of a steel bar can be calculated using its dimensions and the density of steel.
The weight of a steel bar can be calculated using the formula: weight = volume × density
The volume of a steel bar can be calculated using the formula: volume = length × area
The area of a steel bar can be calculated using the formula: area = π × (diameter/2)^2
The density of steel is typically around 7850 kg/m^3

The unit weight of concrete refers to its density or weight per unit volume.
Unit weight of concrete is typically measured in pounds per cubic foot (lb/ft³) or kilograms per cubic meter (kg/m³).
The unit weight of concrete depends on the mix design, which includes the proportions of cement, aggregates, and water.
For example, normal weight concrete typically has a unit weight of about 145 lb/ft³ (2320 kg/m³).

OOPs concepts in Java are the fundamental principles of object-oriented programming.
Encapsulation: wrapping data and code into a single unit
Inheritance: creating new classes from existing ones
Polymorphism: using a single interface to represent multiple types
Abstraction: hiding implementation details from the user
Examples: class, object, inheritance, polymorphism, encapsulation
