Sterling & Wilson Senior Engineer Mechanical Interview Questions and Answers

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

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

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
