- Q1. What project you worked on during your academics?
- Q2. Is propeller shaft of a vehicle is hollow or solid?
- Ans.
Propeller shaft of a vehicle is usually hollow to reduce weight and improve fuel efficiency.
Propeller shafts are typically hollow to reduce weight and improve fuel efficiency
Hollow propeller shafts are commonly used in modern vehicles
Solid propeller shafts are heavier and less efficient
- Q3. What is first and third angle projection method?
- Ans.
First and third angle projection methods are techniques used in engineering drawings to represent a 3D object on a 2D plane.
First angle projection method is commonly used in Europe and Asia, where the object is imagined to be in the first quadrant of a Cartesian coordinate system.
Third angle projection method is commonly used in North America, where the object is imagined to be in the third quadrant of a Cartesian coor...
- Q4. What is joules law of heating?
- Ans.
Joule's law of heating states that the heat produced in a conductor is directly proportional to the square of the current flowing through it, the resistance of the conductor, and the time for which the current flows.
Heat produced (Q) = I^2 * R * t
Where Q is the heat produced, I is the current, R is the resistance, and t is the time.
The law helps in understanding the relationship between electrical energy and heat gener...
- Q5. Types of welding?
- Ans.
Types of welding include MIG, TIG, stick, and flux-cored welding.
MIG welding uses a wire electrode and shielding gas.
TIG welding uses a tungsten electrode and inert gas.
Stick welding uses a consumable electrode coated in flux.
Flux-cored welding uses a tubular wire filled with flux.
Other types include spot welding, laser welding, and resistance welding.
- Q6. What is resistant welding?
- Ans.
Resistance welding is a welding process that joins metal parts by applying pressure and passing current through them.
Resistance welding uses heat generated by resistance to electric current to join metal parts.
Common types of resistance welding include spot welding, seam welding, and projection welding.
It is widely used in automotive, aerospace, and electronics industries.
Resistance welding is a fast and efficient meth...
- Q7. What is a transformer?
- Ans.
A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are commonly used to step up or step down voltage in electrical power distribution.
They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core.
The primary coil is connected to a source of alternating current, which creates a changing magnetic field...
- Q8. What type of transformer do we use in resistance welding? Either Step Up or Step Down?
- Ans.
Step Down transformer is used in resistance welding.
Step Down transformer reduces the voltage from the power source to a lower voltage suitable for welding.
It helps in providing the high current needed for welding without overheating the equipment.
Example: In resistance spot welding, Step Down transformers are commonly used.
- Q9. What is step down transformer?
- Ans.
A step down transformer is a type of transformer that decreases the voltage from primary winding to secondary winding.
Step down transformers have more turns in the primary winding than in the secondary winding.
They are used to reduce the voltage for various applications such as in household appliances.
Example: A step down transformer may convert 220V to 110V for use in the United States.

- Q1. Write logic of AND gate
- Ans.
AND gate is a logic gate that outputs true only when all of its inputs are true.
AND gate has two or more inputs and one output.
The output of an AND gate is true only if all of its inputs are true.
The truth table for an AND gate is: 0 AND 0 = 0, 0 AND 1 = 0, 1 AND 0 = 0, 1 AND 1 = 1.
AND gate can be represented using a logical expression like: output = input1 AND input2 AND ... AND inputN.

- Q1. What is PID and all about previous experience
- Ans.
PID stands for Proportional-Integral-Derivative. It is a control algorithm used in engineering to regulate processes.
PID is a feedback control algorithm that continuously calculates an error value and adjusts the control effort to minimize the error.
It consists of three terms: Proportional, Integral, and Derivative, which are combined to calculate the control output.
The Proportional term responds to the current error, ...

- Q1. Difference between open loop and closed loop?
- Ans.
Open loop does not have feedback mechanism, while closed loop does.
Open loop system does not have a feedback mechanism to adjust the output based on the input.
Closed loop system uses feedback from the output to control the input and maintain desired output.
Open loop systems are simpler and less accurate, while closed loop systems are more complex but more accurate.
Example: A toaster is an open loop system as it does no...
- Q2. What is equation of PID controller
- Ans.
The equation of a PID controller is a control loop feedback mechanism used in industrial control systems.
The equation for a PID controller is: u(t) = Kp*e(t) + Ki*∫e(t)dt + Kd*de(t)/dt
Kp, Ki, and Kd are the proportional, integral, and derivative gains respectively
The proportional term Kp reacts to the current error value
The integral term Ki reacts to the accumulation of past errors
The derivative term Kd reacts to the r
- Q3. Name any two pressure sensors
- Ans.
Two common pressure sensors are piezoresistive sensors and capacitive sensors.
Piezoresistive sensors: measure pressure by changes in electrical resistance
Capacitive sensors: measure pressure by changes in capacitance
- Q4. Difference between open loop and closed loop
- Ans.
Open loop does not have feedback mechanism, while closed loop does.
Open loop system does not have a feedback mechanism to adjust the output based on the input.
Closed loop system uses feedback from the output to adjust the input and maintain desired output.
Examples of open loop systems include a toaster or a washing machine with a timer setting.
Examples of closed loop systems include a thermostat controlling room temper
