Dignizant Technologies Interview Questions and Answers

Yield point is the stress at which a material begins to deform plastically.

• Yield point is the point on a stress-strain curve where the material starts to deform plastically.

• It is the stress at which the material no longer behaves elastically.

• The yield point is important in determining the strength and ductility of a material.

• The yield point can be determined by plotting a stress-strain curve and finding the point where the curve starts to deviate from a straight line.

4-stroke engine and diesel Otto cycle explained

• A 4-stroke engine completes a cycle in four strokes: intake, compression, power, and exhaust

• Diesel Otto cycle is a thermodynamic cycle used in diesel engines

• Diesel Otto cycle consists of four processes: intake, compression, power, and exhaust

• The main difference between gasoline and diesel engines is the way fuel is ignited

• Gasoline engines use spark plugs to ignite the fuel, while diesel engines use compression to ignite the fuel

The 14th law of management is the law of balance.

• The law of balance states that there should be a balance between the needs of the organization and the needs of the individuals working in it.

• It emphasizes the importance of maintaining a balance between the different aspects of management such as planning, organizing, staffing, directing, and controlling.

• The law of balance also stresses the need for a balance between short-term and long-term goals, as well as between efficienc...read more

Concurrent force is the combination of two or more forces acting on a single point simultaneously.

• Concurrent force is a vector quantity.

• The resultant of concurrent forces can be found using the parallelogram law of vector addition.

• Examples of concurrent forces include the forces acting on a seesaw or a crane.

• The point of intersection of the concurrent forces is called the point of concurrency.

There are several types of beams used in construction, including I-beams, H-beams, and T-beams.

• I-beams are also known as W-beams and are shaped like an I

• H-beams are shaped like an H and are commonly used in construction

• T-beams are shaped like a T and are used in construction for bridges and other structures

• Other types of beams include box beams, channel beams, and angle beams
