I appeared for an interview in Feb 2025.
Different types of starters include DOL starter, star-delta starter, auto transformer starter, and soft starter.
Direct Online (DOL) starter: provides full voltage to the motor at start
Star-delta starter: reduces the starting current by initially connecting the motor in star configuration and then switching to delta
Auto transformer starter: uses an auto transformer to reduce the voltage during starting
Soft starter: grad...
A,B,C & D type switchgears are different classifications based on their design and application in electrical systems.
A type switchgears are suitable for low voltage applications
B type switchgears are designed for medium voltage applications
C type switchgears are used for high voltage applications
D type switchgears are specifically designed for extra high voltage applications
Power and control wiring of star delta starter involves connecting the motor to the power supply and control circuit using a specific wiring diagram.
Power wiring involves connecting the three-phase power supply to the motor through the main contactor.
Control wiring involves connecting the control circuit to the motor through the timer and the star-delta contactor.
During starting, the motor is connected in star configur...

Gear ratio is the ratio of the number of teeth on the driving gear to the number of teeth on the driven gear.
Gear ratio determines the speed and torque relationship between two gears.
It is calculated by dividing the number of teeth on the driving gear by the number of teeth on the driven gear.
A gear ratio greater than 1 indicates a reduction in speed and an increase in torque, while a ratio less than 1 indicates an inc...
The symbol of first angle method is a triangle with the vertex pointing downwards. The symbol of third angle method is a triangle with the vertex pointing upwards.
First angle method is commonly used in Europe and Asia while third angle method is commonly used in North America.
In first angle method, the object is placed in the first quadrant while in third angle method, the object is placed in the third quadrant.

The K factor is a value used in sheet metal design to determine the amount of springback that occurs during bending.
The K factor is a ratio that relates the neutral axis to the material thickness.
It is used to calculate the bend allowance and bend deduction in sheet metal bending operations.
A higher K factor indicates more springback, while a lower K factor indicates less springback.
Different materials and bending proc...
Spring back effect is the tendency of a material to return to its original shape after being deformed.
Spring back effect occurs when a material is bent or stretched and then released, causing it to return to its original shape.
It is commonly observed in materials like metals and polymers.
The amount of spring back depends on the material's elasticity and the magnitude of the deformation.
Spring back can be a desirable or...
Machining operations involve using various tools and techniques to shape and cut raw materials into the desired shape and size.
The job may involve using lathes, milling machines, grinders, or other specialized equipment.
The machinist must carefully measure and mark the material before cutting or shaping it.
The machinist may need to use different cutting tools or techniques depending on the material being worked on.

There are various types of gearboxes including spur, helical, bevel, worm, planetary, and cycloidal.
Spur gearboxes have straight teeth and are the simplest type.
Helical gearboxes have angled teeth and are quieter than spur gearboxes.
Bevel gearboxes are used for changing the direction of power transmission.
Worm gearboxes have a screw-like gear and are used for high reduction ratios.
Planetary gearboxes have multiple gear...
