Electromech Infraprojects Executive Design Engineer Interview Questions and Answers

Discussion on soil mechanics starting from modulus of elasticity to liquifaction

• Modulus of elasticity is a measure of soil stiffness

• Soil strength is important in determining its ability to withstand loads

• Liquifaction occurs when soil loses strength and behaves like a liquid

• Factors affecting soil strength include soil type, moisture content, and stress history

• Liquifaction can lead to soil failure and damage to structure

Grade M25 is a mix of concrete with a compressive strength of 25 megapascals after 28 days.

• M25 is a standard mix of concrete used in construction.

• It is made up of 1 part cement, 1 part sand, and 2 parts coarse aggregate.

• It has a compressive strength of 25 MPa after 28 days of curing.

• It is commonly used in the construction of buildings, bridges, and other structures.

• M25 is suitable for moderate exposure conditions and c

The question covers power factor of transformer, types of DC machine, working principle of AC alternator, and DC motors.

• Power factor of a transformer is the ratio of real power to apparent power.

• Types of DC machines include DC motors and DC generators.

• AC alternators work on the principle of electromagnetic induction to convert mechanical energy into electrical energy.

• DC motors convert electrical energy into mechanical ...read more
