Odisha Hydro Power Corporation Interview Questions, Process, and Tips

Bending moment is the measure of the bending effect on a beam when an external force is applied to it.

• Bending moment is the product of the force applied and the distance from the force to the point of support.

• It causes the beam to bend and can lead to failure if the stress exceeds the material's strength.

• Cantilever beams have one end fixed and the other end free, making them more susceptible to bending moments.

• Bending ...read more

Forced vibration depends on time function due to the periodic nature of the external force.

• Forced vibration is caused by an external force acting on a system.

• The external force is usually periodic in nature.

• The response of the system to the external force is also periodic.

• The time function of the external force determines the frequency and amplitude of the system's response.

• Examples include a car driving over a speed b

Otto cycle and Brayton cycle are thermodynamic cycles used in internal combustion engines and gas turbines respectively.

• Otto cycle is a four-stroke cycle used in spark-ignition engines.

• It consists of four processes: intake, compression, power, and exhaust.

• Brayton cycle is a thermodynamic cycle used in gas turbines.

• It consists of four processes: compression, combustion, expansion, and exhaust.

• Both cycles involve the con

Derive power equation in pipe flow for given head.

• Power equation in pipe flow is given by P = Q * H * ρ * g

• Where P is power, Q is flow rate, H is head, ρ is density and g is acceleration due to gravity

• Power equation can be derived using Bernoulli's equation and conservation of energy principle

Follow up matrix tracks progress of tasks in a project. Critical path is the longest path in the project that determines the project duration.

• Follow up matrix helps in identifying the status of each task in a project and ensures timely completion.

• Critical path analysis helps in identifying the tasks that are critical to the project timeline and need to be completed on time.

• By focusing on the critical path, project mana...read more

Welding electrode parameters and code for overhead welding.

• Welding electrode parameters include diameter, current type, and coating type.

• For overhead welding, the given code is AWS D1.3.

• Electrode diameter should be smaller for overhead welding to prevent dripping.

• Coating type should be low-hydrogen for overhead welding to prevent porosity.

• Current type should be DC- for overhead welding to prevent arc blow.
