Q2. What is payback period?
Ans. 
Payback period is the time it takes for an investment to generate enough cash flow to cover its initial cost.
• Payback period is a financial metric used to evaluate the time it takes for an investment to recoup its initial cost.

• It is calculated by dividing the initial investment by the annual cash inflows generated by the investment.

• A shorter payback period is generally preferred as it indicates a quicker return on inves...read more

Q2. Different grades of concrete
Ans. 
Different grades of concrete refer to the strength and quality of the concrete mix.
• Different grades of concrete are designated by their strength in megapascals (MPa), such as M20, M30, etc.

• Higher grade concrete has a higher strength and is typically used for structural purposes.

• Lower grade concrete is suitable for non-structural applications like paving or flooring.

• The mix proportions and ingredients vary for different...read more

Q1. What is Full form of SBC
Ans. 
SBC stands for Safe Bearing Capacity.
• SBC is the maximum pressure that can be applied to the soil without risk of shear failure.

• It is an important factor in the design of foundations for structures.

• For example, if the SBC of a soil is 200 kN/m^2, it means that the soil can safely support a load of 200 kN per square meter.
