Sansera Engineering Mechanical Technician Interview Questions and Answers

The hydraulic system is a technology that uses liquid to transmit power.

• Uses incompressible fluid to generate force

• Consists of a pump, fluid reservoir, valves, cylinders, and motors

• Commonly used in heavy machinery like excavators and hydraulic presses

Backlash is the clearance or lost motion between mechanical components, typically in gears or threads.

• Backlash is the amount of free movement or play between components in a mechanical system.

• It can be found in gears, threads, or any other mechanical connection where there is a gap between mating parts.

• Backlash can affect the accuracy and precision of a mechanical system.

• It is important to minimize backlash in precisio...read more

Why-why Analysis is a problem-solving technique that involves asking 'why' multiple times to get to the root cause of an issue.

• Involves asking 'why' repeatedly to uncover the underlying causes of a problem

• Helps in identifying the root cause of an issue rather than just addressing symptoms

• Commonly used in quality management and process improvement

• Example: If a machine breaks down - Why? Because a part failed - Why? Beca...read more

Backlash in axis refers to the clearance or play between mating components in a mechanical system.

• Backlash is the amount of movement or play between components in a mechanical system.

• It can affect the accuracy and precision of the system.

• Backlash can be minimized by using precision components or adjusting the system properly.

• For example, in a gear system, backlash can cause inaccuracies in positioning if not properly a

There are several types of bearings used in mechanical applications.

• Plain bearings

• Rolling element bearings (ball bearings, roller bearings)

• Thrust bearings

• Sleeve bearings

• Needle bearings

• Tapered roller bearings

• Spherical roller bearings

There are several types of hydraulic pumps, including gear pumps, vane pumps, piston pumps, and screw pumps.

• Gear pumps are simple and economical, but not very efficient.

• Vane pumps are more efficient and quieter than gear pumps.

• Piston pumps are highly efficient and can handle high pressures.

• Screw pumps are used for high viscosity fluids and can handle high pressures as well.

I ride a road bike for commuting and a mountain bike for leisure.

• I prefer road bikes for their speed and efficiency on paved roads.

• I enjoy mountain biking for the challenge and adventure of off-road trails.

• I also have experience with hybrid bikes for their versatility.

• I prioritize safety and always wear a helmet and follow traffic laws.

• I have participated in charity rides and group rides for fun and community.

Vehicle testing involves various methods to ensure safety, performance, and compliance with regulations.

• Testing can include physical tests such as crash tests, durability tests, and performance tests.

• Simulation and modeling can also be used to test vehicle components and systems.

• Testing must comply with regulations set by organizations such as the National Highway Traffic Safety Administration (NHTSA) and the European

We conduct various types of homologation testing depending on the product and its intended market.

• We conduct safety testing to ensure compliance with local regulations.

• We perform emissions testing to ensure compliance with environmental regulations.

• We conduct performance testing to ensure the product meets the required standards.

• We also conduct durability testing to ensure the product can withstand the expected wear an...read more
