Sterling & Wilson Senior Technician Interview Questions and Answers

The unit weight of steel refers to the weight of a specific volume of steel.

• Unit weight is typically measured in pounds per cubic foot or kilograms per cubic meter.

• The unit weight of steel can vary depending on the type and grade of steel.

• For example, the unit weight of mild steel is approximately 7850 kilograms per cubic meter.

• The unit weight of stainless steel is higher, ranging from 7480 to 8000 kilograms per cubic ...read more

Grade of concrete and reinforcement diameter are important factors in civil engineering design.

• The grade of concrete determines its strength and durability.

• Common grades of concrete include M20, M25, and M30.

• Reinforcement diameter affects the strength and stability of the structure.

• Common reinforcement diameters include 8mm, 10mm, and 12mm.

• The appropriate grade of concrete and reinforcement diameter depend on the speci

Leveling is the process of determining the height or elevation of a point or surface relative to a reference point.

• Leveling is commonly used in civil engineering and construction to ensure accurate measurements and proper alignment.

• It involves the use of leveling instruments such as a level, theodolite, or laser level.

• The process typically includes setting up benchmarks or reference points, taking readings at different...read more

The diameter of six mm refers to the size or measurement of a circular object that is six millimeters in width.

• The diameter is the distance across the center of a circle, passing through the circumference.

• A six mm diameter can be visualized as a circle with a width of six millimeters.

• It is a common measurement used in various industries, including engineering and manufacturing.

• For example, a six mm diameter steel rod w...read more

LEP stands for Load Equivalent Factor for Pavement design.

• LEP is used in pavement design to determine the load-carrying capacity of the pavement.

• The formula for LEP depends on the specific design method being used.

• For example, in the AASHTO design method, LEP is calculated using the formula: LEP = (ESAL/1000) * (1 + 0.003 * (T - 3))

• Here, ESAL is the Equivalent Single Axle Load and T is the pavement design period in yea...read more
