Are you an aspiring mechanical engineer? If yes, then you must be aware of the top 10 mechanical design engineer interview questions that are asked in almost every interview. Most of the questions focus on the basic concepts of mechanical engineering, but there are also a few that focus on the specific skills required for the job.
Knowing the answers to these questions will not only help you prepare for the interview but also help you understand the role of a mechanical engineer better. So, without further ado, let's take a look at the top 10 interview questions for design mechanical engineer that you must be aware of.
Answer: Prosthetics, industrial and architectural design, shipbuilding, automobile and aerospace manufacturing, and many more fields employ CAD, which is a crucial industrial art.
Answer: Product development is a preliminary process where all of the design documentation is created depending on the expectations of the client, market, and budget. Manufacturing tools including machine tools, molds, etc. are needed for production. If none already exist, we will have to create them.
The manufacturing equipment must then be purchased or created, which might take a long time and be expensive. Production, which includes part production and assembly, is the final step.
Answer: The purpose of this mechanical engineering interview question is for the interviewer to learn more about your viewpoint. You might respond, "Out of all the skills that a mechanical engineer must possess, the most significant is a problem-solving skill," or anything along those lines. In order to address a problem, a person must be able to consider several options and make decisions about what might happen. Additionally, they must be creative and attempt other methods if the first one doesn't work.
Answer: While I was in college, I worked on a project to build a hand pump. Under the direction of the HOD, a group of six students conducted an extensive study before drawing and writing stage-by-stage project reports. Overall, the experience was enjoyable and instructive.
Here, the interviewer checks whether the candidate actively participated in college group assignments. If the answer sounds satisfactory, now the applicant faces a round of technical analysis.
Answer: Both hydraulic and pneumatic systems use fluid power, but there are some very important distinctions between them. For example:
Answer: An electric motor and an electric generator are identical in their basic operation. All motors function like generators in our everyday lives, and all generators act like motors.
However, an electric generator produces electrical energy, as the name says. An electric motor consumes electricity. Aside from that, an electric generator converts mechanical energy into electrical energy and an electric motor converts electrical energy into mechanical energy.
Answer: A thermodynamic cycle that transforms heat into mechanical energy is the Rankine cycle, often known as the Rankine vapour cycle. William Johnson Macquorn Rankine, a Scottish engineer and physicist best known for his studies of the thermodynamic characteristics of steam, is the name-bearer of the Rankine cycle.
A Rankine cycle system consists of four components: a pump, a boiler, a turbine, and a condenser. The pump's responsibility is to pressurize water and send itsupply liquid to the boiler. The function of the boiler is to heat the waterliquid and convert it to steamvapour. A turbine is then driven by the steam generated in boilervapour. The turbine's task is to convert the kinetic energy of steam to mechanical energyheat energy from the heated fluid into useful energy. The steamvaporised liquid is subsequently cooled in the condenser so that it returns to a liquid state. The condenser's liquid is inflated by the pump, and the cycle keeps going.
Answer: A two-dimensional representation of a three-dimensional object is called an orthographic sketch. The lines are orthogonal to the projection plane.
We witness objects from every angle, just as one would perceive them in three dimensions. This helps with the manufacturing process by allowing for easier management of the hidden features and linking components that are difficult to see in a three-dimensional item.
Answer: There are numerous varieties of screws. When working with wood, wood screws composed of bronze, brass, or steel are employed.
For drywall panels, drywall screws are utilised. W-type screws and S-type screws are the two varieties available.
Self-tapping screws can be used as metal sheet screws, wood screws, or drywall screws. They are employable without a drill.
Metal sheet screws are all-purpose fasteners that can be used to join rubber, plastic, metal, or plywood anywhere.
Pre-drilling is necessary for masonry screws since they lack a pointed end.
Answer: A man-made heat-exchanger system is used in the mechanical refrigeration process to remove heat from a system. This refrigeration system could be magnetic, thermoelectric, cyclic, or non-cyclic. The use for which refrigeration is required determines the answer. It is also known as Carnot Cycle which is a perfect closed thermodynamic cycle that involves isothermal expansion to a desired set point, adiabatic extension to a desired location, isothermal compression, and adiabatic contraction back to the starting state for the working substance.
The average salary of a mechanical engineer in India is around 4 lacs per annum.Because the fundamentals of technicality are crucial, the level of design engineer interview questions and answers is significantly greater than that of other interview questions.
