Ques:- Why do people sitting inside a train not get shocked, while someone on top may get an electric shock? How does train earthing work?
Asked In :-
Right Answer:

People inside the train don’t get shocked because they’re not in direct contact with the high-voltage overhead wires. Trains use a pantograph on top to draw power (often 25,000 volts AC) from the overhead line. That current flows through the train’s internal electrical system and returns to the ground through the rails.

☝ The metal body of the train is insulated from the high-voltage system, and passengers are safely inside.

⚡ A person on top of the train is dangerously close to the live wire. Even without touching it, the high voltage can arc through the air and cause a deadly shock.

🔌 Earthing in trains:
Electric trains complete the circuit using the track as a return path. The rails are grounded (earthed) at intervals to safely carry current back to the substation.

Ques:- How much time is required for completion of boiler structure erection?
Asked In :- pqc, carl zeiss ab,
Right Answer:

The time required to complete boiler structure erection depends on the boiler size, type, and site conditions. On average, it takes about 4 to 6 months for a medium to large industrial boiler.

Ques:- How to generate steam?
Asked In :-
Right Answer:

Steam is generated by heating water in a closed container (called a boiler) until it boils and turns into vapor. This is usually done using fuels like coal, gas, oil, or electricity.

Ques:- What do you know about the process, mechanical basics, and manufacturing requirements of various products?
Right Answer:

Understanding manufacturing means knowing how raw materials are turned into final products. It includes:

1. Mechanical Basics:
Concepts like force, torque, motion, friction, stress-strain, thermodynamics, and material strength.

2. Process Knowledge:
Includes casting, machining, welding, forging, molding, assembly, and quality control.

3. Product Manufacturing:
Each product has specific needs—like tolerance, surface finish, material selection, and safety checks.

Ques:- How much steam is produced from 1 kg of coal?
Asked In :-
Right Answer:

On average, 1 kg of coal produces around 5 to 6.5 kg of steam, depending on the coal quality and boiler efficiency.


Ques:- Question: Principle of turbine. How overspeed device works? How rotor remains at center? How alignment is done?
Right Answer:

1. Principle of Turbine:
A turbine works on Newton’s third law — when steam, water, or gas flows over the blades, it pushes them, causing the rotor to spin and generate energy.

2. Overspeed Device:
It automatically shuts down the turbine if it rotates too fast, protecting it from damage. It uses sensors to detect speed and trigger a trip mechanism.

3. Rotor Centering:
The rotor stays centered using journal bearings and proper balancing. Any wobble is controlled by oil film damping in the bearings.

4. Alignment:
Alignment is done using laser or dial gauges to ensure the rotor and shaft are straight and centered during installation. Proper alignment prevents vibration and wear.

Ques:- Your area of interest in studies?
Asked In :- Rams Engineers, metrohm,

Ques:- How many types of welding are there?
Right Answer:

There are four main types of welding:

1. Arc Welding (like MIG & TIG)
2. Gas Welding (like oxy-acetylene)
3. Resistance Welding (like spot welding)
4. Energy Beam Welding (like laser or electron beam)

Each type is used based on the materials and purpose.

Ques:- Else everything was related to personal?
Asked In :- vector informatik gmbh,

A Site or Field Mechanical Engineer is a crucial professional who operates on the front lines of construction, manufacturing, or industrial projects. Their primary role is to be the on-site expert for all mechanical systems and equipment. Unlike an office-based design engineer, a field engineer’s work is hands-on and focused on the practical implementation and successful execution of mechanical engineering plans in a real-world environment. This role is a vital link between the design phase and the construction or operational phase of a project, ensuring that what was conceived on paper is built correctly and safely.

The responsibilities of a Site/Field Mechanical Engineer are diverse and can vary depending on the industry, such as in oil and gas, power generation, or building construction. Key duties typically include:

  • Supervising Installation: The engineer oversees the installation, testing, and commissioning of all mechanical equipment, such as HVAC systems, pumps, pipes, turbines, and machinery. They are responsible for ensuring that all work is done according to the project’s technical specifications and blueprints.
  • Quality Control and Compliance: They conduct regular inspections to ensure that materials, workmanship, and installation procedures meet the highest standards of quality and comply with all relevant safety regulations and engineering codes. They are often the final authority on accepting or rejecting a component’s installation.
  • Problem-Solving and Troubleshooting: On a project site, unforeseen challenges are common. The engineer must be adept at diagnosing and solving mechanical problems as they arise. This could involve troubleshooting equipment malfunctions, resolving conflicts in design with site conditions, or providing quick, effective solutions to keep the project on schedule.
  • Coordination and Communication: The role requires constant communication with various stakeholders, including project managers, contractors, other engineers (e.g., civil or electrical), and vendors. They must effectively communicate progress, report on issues, and ensure that all parties are aligned on the mechanical aspects of the project.
  • Safety Management: A paramount responsibility is ensuring safety on-site. The engineer must enforce safety protocols related to the installation and operation of mechanical systems, conduct safety briefings, and ensure that all equipment is operated correctly to prevent accidents.

A successful Site/Field Mechanical Engineer must possess not only a strong foundation in mechanical engineering principles but also exceptional problem-solving skills, excellent communication abilities, and the capacity to work under pressure. Their practical expertise and decision-making on-site are instrumental in the successful, timely, and safe completion of any project with mechanical components.
