Lear Corporation Senior Cost Engineer Interview Questions and Answers

Q1. What is draft angel & Shutoff and Difference
Ans. 
Draft angle is the angle of the vertical wall of a mold or part, while shutoff is the point where two mold halves meet to prevent material flow.
• Draft angle is necessary for easy ejection of parts from molds.

• Shutoff is crucial for preventing material leakage and ensuring part accuracy.

• Draft angle is typically around 1-3 degrees, while shutoff is a precise meeting point of mold halves.

• Examples: Draft angle - plastic inje

Q1. What is the relay
Ans. 
A relay is an electrically operated switch that uses an electromagnet to mechanically operate a switch.
• Relays are used to control high power circuits with low power signals

• They are commonly used in automotive, industrial, and household applications

• Relays can be classified based on their operation, such as electromechanical relays or solid-state relays

Q2. Ohm's law and current
Ans. 
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, given constant resistance.
• Ohm's law equation: V = I * R (voltage = current * resistance)

• Current is the flow of electric charge through a conductor

• Higher voltage leads to higher current flow, given constant resistance

• Lower resistance leads to higher current flow, given constant voltage

Q1. What is the teransform
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 levels in electrical systems.

• They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core.

• The primary coil is connected to the input voltage source, while the secondary coil is connected to the outpu...read more

Q3. What is the voltage
Ans. 
Voltage is the difference in electric potential between two points.
• Voltage is measured in volts (V).

• It represents the potential energy per unit charge.

• Voltage is the driving force that pushes electric current through a circuit.

Q4. What is the ohm's low
Ans. 
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.
• Ohm's Law is represented by the formula V = IR, where V is the voltage, I is the current, and R is the resistance.

• It helps in calculating the current flowing through a circuit when the voltage and resistance are known, or determining the r...read more
