If tensile stress of a steel rod of diameter is 1400 kg/cm2 and bond stress is 6 kg/cm2, the required bond length of the rod is

Estimating is the technique of calculating or Computing the various quantities and the expected Expenditure to be incurred on a particular work or project.

The goal of each cost estimation method is to estimate fixed and variable costs and to describe this estimate in the form of Y = f + vX. That is, Total mixed cost = Total fixed cost + (Unit variable cost × Number of units).
