Wipro PARI Additive Manufacturing Engineer Interview Questions and Answers

Q1. What is difference between == and ===?
Ans. 
The difference between == and === is that == compares the values of two variables, while === compares both the values and the data types.
• The == operator performs type coercion, meaning it converts the operands to a common type before comparison.

• The === operator does not perform type coercion and requires both the values and the data types to be the same for a true comparison.

• For example, 1 == '1' returns true because t...read more

Q2. What is mean by relay and how it operates?
Ans. 
A relay is an electrically operated switch that uses an electromagnet to mechanically operate the switch contacts.
• Relays are used to control high power circuits with a low power signal.

• When the coil of the relay is energized, it creates a magnetic field that causes the switch contacts to close or open.

• Relays are commonly used in automotive applications, industrial controls, and home appliances.

• There are different types...read more

Q1. What is k factor & y factor
Ans. 
K factor and Y factor are parameters used in sheet metal bending to calculate the bend allowance and bend deduction.
• K factor is the ratio of the neutral axis to the material thickness in a bend.

• Y factor is the ratio of the inside radius of the bend to the material thickness.

• K factor is used to calculate bend allowance, while Y factor is used to calculate bend deduction.

• Both factors are important in determining the fina
