Capgemini Interview Questions and Answers

Various types of plastics are used in design engineering, each with unique properties and applications.

• Common types include ABS, polycarbonate, polypropylene, and PVC

• Each type has different strengths, flexibility, and heat resistance

• Plastics are chosen based on factors like cost, durability, and desired properties

Grade of cement refers to the strength of cement. It is classified into different grades based on its compressive strength.

• Grade of cement is denoted by a number followed by Mpa (megapascal)

• The higher the grade, the higher the compressive strength of cement

• For example, grade 53 cement has a compressive strength of 53 Mpa

• Different grades of cement are used for different construction purposes

There is no formula for steel, but its properties can be calculated using various equations.

• Steel is an alloy of iron and carbon, with other elements added for specific properties.

• The properties of steel can be calculated using equations such as Young's modulus, Poisson's ratio, and thermal expansion coefficient.

• The strength of steel can be calculated using the ultimate tensile strength formula.

• Steel's corrosion rate can be calculated using the Nernst equation.

• Steel's hardnes...read more

Cube size refers to the dimensions of a cube-shaped object.

• Cube size is typically measured in length, width, and height.

• It is commonly used in construction and engineering for materials such as concrete blocks.

• For example, a standard concrete block may have a cube size of 8 inches by 8 inches by 8 inches.

Types of cement include Portland cement, white cement, rapid hardening cement, and low heat cement.

• Portland cement is the most commonly used type of cement and is used in general construction.

• White cement is used for decorative purposes and has a high degree of whiteness.

• Rapid hardening cement is used in projects where quick setting is required.

• Low heat cement is used in large concrete projects to prevent cracking due to heat.

Pressure is the force applied per unit area, while stress is the force applied per unit area of a material.

• Pressure is a scalar quantity, while stress is a tensor quantity.

• Pressure is measured in units of force per unit area, while stress is measured in units of force per unit area of a material.

• Pressure is a measure of the external force applied to an object, while stress is a measure of the internal force within a material.

• Examples of pressure include atmospheric pressure, ...read more
