Unit weight of steel is the weight of a unit volume of steel.
Unit weight of steel is typically measured in kilograms per cubic meter (kg/m³).
The unit weight of steel varies depending on the type of steel and its composition.
For example, the unit weight of mild steel is approximately 7850 kg/m³.
The unit weight of stainless steel is approximately 7480 kg/m³.
The unit weight of high-strength steel can be as high as 8000 kg
Quantities of cement, sand, and coarse aggregate depend on the mix design and required strength of concrete.
The mix design determines the ratio of cement, sand, and coarse aggregate.
The strength of concrete required also affects the quantities of materials used.
The water-cement ratio is also an important factor in determining the quantities of materials.
The quantities are usually expressed in terms of weight or volume.

Motors are rated in KW because they consume power, while transformers and generators are rated in KVA because they produce power.
Motors convert electrical energy into mechanical energy, so they consume power and are rated in KW.
Transformers and generators produce electrical energy, so they are rated in KVA based on their apparent power.
KVA takes into account both the real power (KW) and the reactive power (KVAR) produc...
The type of motor used in ceiling fans is an induction motor.
Ceiling fans typically use single-phase induction motors.
These motors are designed to provide a constant speed and are efficient in converting electrical energy into mechanical energy.
The motor consists of a stator and a rotor, with the stator being the stationary part and the rotor being the rotating part.
The stator contains windings that create a rotating m...
A thermal power plant generates electricity by converting heat energy into mechanical energy.
Thermal power plants use fossil fuels or nuclear energy to heat water and produce steam.
The steam drives a turbine, which is connected to a generator that produces electricity.
The heat source can be coal, natural gas, oil, or nuclear reactions.
The steam is condensed back into water and recycled in a closed-loop system.
Thermal p...
A program to generate a geometric progression (GP).
Take the first term, common ratio and number of terms as input.
Use a loop to calculate each term of the GP.
Print the generated GP as output.
A program to print factorial using recursion
Define a function to calculate factorial recursively
Base case: if the number is 0 or 1, return 1
Recursive case: multiply the number with factorial of (number - 1)
Print the factorial of a given number
