I applied via Naukri.com and was interviewed before May 2018. There were 5 interview rounds.
Open loop and closed loop are two modes of operation in hydraulic systems.
Open loop operation: The hydraulic system operates without feedback control. The output is not adjusted based on the system's performance.
Closed loop operation: The hydraulic system uses feedback control to adjust the output based on the system's performance.
Open loop systems are simpler and less expensive, but they lack precision and accuracy.

The starting circuit is responsible for initiating the engine's operation.
The starting circuit consists of components such as the battery, starter motor, ignition switch, and solenoid.
When the ignition switch is turned on, it sends a signal to the solenoid, which then engages the starter motor.
The starter motor uses electrical energy from the battery to turn the engine's crankshaft, starting the combustion process.

Numerical questions and reasoning
General tolerances refer to the acceptable range of variation in dimensions or properties of a part or product.
General tolerances are typically specified in engineering drawings to ensure parts fit and function properly.
They are usually expressed as a range of acceptable values, such as +/- 0.1mm.
Tolerances can vary depending on the specific requirements of the part or product.
Examples of general tolerances include dim...
The material for wheel is typically rubber or plastic, while the material for pin is usually metal such as steel or aluminum.
Wheel material is commonly rubber or plastic for flexibility and durability
Pin material is usually metal like steel or aluminum for strength and stability
Hardware grades are typically classified based on material composition, strength, and corrosion resistance.
Hardware grades are often denoted by a combination of letters and numbers, such as Grade 8.8 or Grade 316.
Higher grade numbers generally indicate a higher tensile strength or corrosion resistance.
Common grades for screws include Grade 2, Grade 5, and Grade 8, with Grade 8 being the strongest.
For nuts and washers, ...
Motor power can be calculated using the formula: Power (W) = Torque (Nm) x Speed (RPM) / 9.548
Calculate the torque required for the application
Determine the speed at which the motor will operate
Use the formula Power (W) = Torque (Nm) x Speed (RPM) / 9.548 to calculate motor power
Welds are critical in design engineering for joining metal components together.
Welds must be strong enough to withstand the intended load and stress.
Proper welding techniques and materials must be used to ensure the integrity of the weld.
Inspections and testing should be conducted to verify the quality of the weld.
Consideration should be given to factors such as joint design, welding process, and material compatibility...

A hydraulic circuit is a system that uses pressurized fluid to transmit power.
A hydraulic pump is used to create pressure in the fluid.
Valves control the flow of fluid through the circuit.
Actuators, such as cylinders or motors, convert the fluid pressure into mechanical force.
A reservoir stores the fluid and a filter removes contaminants.
Examples include excavators, cranes, and hydraulic presses.
Tappet setting is the process of adjusting the clearance between the tappet and the valve stem in an engine.
Tappet setting ensures proper valve timing and prevents engine damage.
It involves adjusting the clearance between the tappet and the valve stem using a feeler gauge.
The correct tappet setting varies depending on the engine model and manufacturer.
Incorrect tappet setting can cause engine noise, poor performance, a...

A variable axial piston pump is a type of hydraulic pump that uses a rotating cylinder block with pistons to generate fluid flow.
The pump consists of a cylinder block with multiple pistons arranged in a circular pattern.
As the cylinder block rotates, the pistons move in and out of their respective cylinder bores.
The movement of the pistons creates a reciprocating motion, which draws in and pushes out hydraulic fluid.
