An induction motor is a type of AC motor where power is supplied to the rotor by electromagnetic induction.
Induction motors are commonly used in various industrial applications due to their simplicity and reliability.
They consist of a stator (stationary part) and a rotor (rotating part).
When AC power is supplied to the stator windings, a rotating magnetic field is produced which induces currents in the rotor windings, ...
To convert 230V AC to 24V DC, a rectifier circuit can be used.
Use a step-down transformer to reduce the voltage from 230V AC to a lower voltage.
Connect the output of the transformer to a rectifier circuit to convert AC to DC.
Use a voltage regulator to stabilize the output at 24V DC.
Examples of rectifier circuits include full-wave rectifiers and bridge rectifiers.
PLC stands for Programmable Logic Controller, it is a digital computer used for automation of electromechanical processes.
PLC is used to control machinery in industries by programming it to perform specific tasks.
It consists of input and output modules, a central processing unit, and a programming device.
PLCs use ladder logic programming language to create programs for controlling processes.
They are commonly used in ma...
Programming of PLC involves writing code to control the operation of a programmable logic controller.
PLC programming involves creating logic diagrams to represent the control process.
Programming languages like ladder logic, function block diagram, and structured text are commonly used.
Inputs and outputs are defined in the program to control the operation of machinery or processes.
Programming of PLCs can be done using s...
I applied via Campus Placement and was interviewed in Dec 2022. There were 3 interview rounds.
Hook's law states that the force needed to extend or compress a spring by a certain distance is directly proportional to that distance.
Force is directly proportional to extension or compression
Limitation: Only applicable to linear elastic materials
Does not hold true for materials that exhibit plastic deformation
Example: Stretching a rubber band follows Hook's law until it reaches its elastic limit
There are various operations that can be performed on a lathe machine, including turning, facing, drilling, boring, knurling, and threading.
Turning - used to create cylindrical parts
Facing - used to create a flat surface at the end of a workpiece
Drilling - used to create holes in the workpiece
Boring - used to enlarge existing holes
Knurling - used to create a textured pattern on the surface of the workpiece
Threading - u

I applied via Walk-in and was interviewed in Feb 2020. There were 4 interview rounds.
The unit of pressure is Pascal (Pa).
Pressure is defined as force per unit area.
The SI unit of force is Newton (N) and the SI unit of area is square meter (m²).
Therefore, the SI unit of pressure is Newton per square meter (N/m²) or Pascal (Pa).
Other common units of pressure include pounds per square inch (psi) and atmospheres (atm).

SPC stands for Statistical Process Control, a method used to monitor and control processes to ensure they are operating efficiently and within specifications.
SPC involves collecting and analyzing data to identify variations in a process
It helps in detecting and correcting issues before they result in defects
Common tools used in SPC include control charts, histograms, and Pareto charts
To configure a dp dp coupler, set the parameters for communication protocol, baud rate, address, and data format.
Set the communication protocol to match the devices being connected.
Configure the baud rate to ensure proper data transmission speed.
Assign a unique address to the dp dp coupler for identification.
Choose the appropriate data format for the connected devices.
Test the configuration to ensure proper communicati

I applied via Campus Placement and was interviewed in Jul 2021. There were 4 interview rounds.
Fluid is a substance that flows and takes the shape of its container.
Fluid is a state of matter that has no fixed shape and yields easily to external pressure.
Examples of fluids include water, oil, and air.
Fluids can be classified as liquids or gases based on their properties.
Power is the rate at which work is done or energy is transferred.
Power is measured in watts (W)
It is calculated as the product of voltage and current (P = V x I)
Power can also be calculated as the rate of energy transfer (P = E / t)
Higher power means more work can be done in a shorter amount of time
A machine is a device that uses power to perform a task.
Machines can be simple, like a lever or pulley, or complex, like a computer or car engine.
They are designed to make work easier by transferring force from one point to another.
Examples include washing machines, airplanes, and cranes.
The unit of power is the watt (W), which measures the rate at which work is done or energy is transferred.
The unit of power is the watt (W)
Power is the rate at which work is done or energy is transferred
1 watt is equal to 1 joule per second
Common examples of power include light bulbs (measured in watts) and engines (measured in horsepower)
A unitless quantity is a physical quantity that does not have any units associated with it.
Unitless quantities are often used in mathematical calculations and comparisons.
Examples include angles (measured in radians), pure numbers (such as ratios or percentages), and constants like pi.
Unitless quantities are dimensionless and do not require any specific units for measurement.
