10+ Adani Group Interview Questions and Answers for Freshers

A starter of an induction motor is a device used to control the starting current and torque of the motor.

• The starter helps in reducing the high starting current drawn by the motor.

• It provides a controlled start to the motor, preventing any damage to the motor windings.

• There are different types of starters used for induction motors, such as direct-on-line (DOL) starters, star-delta starters, and auto-transformer starters.

• The starter may include components like contactors, over...read more

Transportation and logistics play a crucial role in the market by ensuring efficient movement of goods and services.

• Transportation helps in connecting producers with consumers by moving goods from one place to another.

• Logistics involves the coordination of resources and processes to ensure timely delivery of products.

• Efficient transportation and logistics can lead to cost savings and improved customer satisfaction.

• Examples: Amazon's efficient delivery network, FedEx's global ...read more

The strength of reinforcement of mild steel is determined by its yield strength and ultimate tensile strength.

• The strength of reinforcement of mild steel is typically around 250 MPa to 600 MPa.

• Yield strength is the point at which the material permanently deforms, while ultimate tensile strength is the maximum stress a material can withstand before breaking.

• Reinforcement bars in construction are commonly made of mild steel due to its good strength and ductility.

Renewable energy is energy that is generated from natural resources that are constantly replenished, such as sunlight, wind, and water.

• Renewable energy is derived from sources that are naturally replenished over a short period of time.

• It is considered sustainable because it does not deplete finite resources.

• Examples of renewable energy sources include solar power, wind power, hydropower, geothermal energy, and biomass.

• Renewable energy helps reduce greenhouse gas emissions and...read more

Wind power is generated by converting the kinetic energy of wind into electrical energy using wind turbines.

• Wind turbines capture the energy from the wind and convert it into rotational motion.

• The rotational motion is then used to spin a generator, which produces electricity.

• Wind power is a renewable energy source that is clean and does not produce greenhouse gas emissions.

• Wind farms consist of multiple wind turbines grouped together to generate larger amounts of electricity....read more

The initial and final setting times of ordinary Portland cement grade 33 vary depending on several factors.

• The initial setting time of cement refers to the time it takes for the cement to harden and develop a certain degree of rigidity.

• The final setting time is the time it takes for the cement to fully harden and reach its maximum strength.

• The setting times can be influenced by factors such as temperature, water-cement ratio, and the presence of additives.

• The specific initial...read more

M-25 ratio is a mix design ratio used in concrete construction.

• M-25 ratio refers to the mix design ratio of concrete, where M represents the compressive strength of concrete after 28 days of curing.

• In M-25 ratio, the ratio of cement, sand, and aggregate is 1:1:2 respectively.

• For example, if we need to prepare 1 cubic meter of M-25 grade concrete, we would require 1/4 cubic meter of cement, 1/4 cubic meter of sand, and 1/2 cubic meter of aggregate.

Dry volume cement is the volume of cement required in a dry state for a given volume of concrete.

• Dry volume cement is calculated by multiplying the volume of cement required by the bulkage factor.

• Bulkage factor is the ratio of the volume of dry cement to the volume of cement in a wet state.

• Dry volume cement estimation is important in determining the quantity of cement required for a construction project.

• For example, if the wet volume of cement required for a project is 1 cubi...read more

The concrete ratio of M15 is 1:2:4 (cement:sand:aggregate).

• M15 is a mix of concrete with a compressive strength of 15 MPa.

• The ratio of cement to sand to aggregate is 1:2:4.

• For example, if you need 1 cubic meter of concrete, you would use 350 kg of cement, 700 kg of sand, and 1400 kg of aggregate.
