Frontman Interview Questions and Answers

1st, 2nd, 3rd, and 4th angle projections are different methods of representing a 3D object on a 2D plane in engineering drawings.

• 1st angle projection: Commonly used in Europe and Asia, where the object is placed in the first quadrant.

• 2nd angle projection: Commonly used in North America, where the object is placed in the fourth quadrant.

• 3rd angle projection: Commonly used in Australia and the UK, where the object is placed in the third quadrant.

• 4th angle projection: Rarely use...read more

Hook's law states that the force needed to extend or compress a spring by a distance is proportional to that distance.

• Force is directly proportional to displacement

• The formula is F = kx, where F is the force, k is the spring constant, and x is the displacement

• The law is applicable to springs, rubber bands, and other elastic materials

FEA is carried out to analyze the behavior of structures under different loading conditions and optimize their design.

• To predict how a structure will react under different loading conditions

• To optimize the design of a structure by identifying areas of high stress

• To reduce the number of physical prototypes needed for testing

• To save time and cost in the design process

• To ensure the safety and reliability of a structure

DFMEA is essential in design to identify and mitigate potential failure modes early in the development process.

• DFMEA helps in identifying potential failure modes and their effects on the system.

• It allows for prioritization of risks based on severity, occurrence, and detection.

• DFMEA aids in developing strategies to mitigate or eliminate identified risks.

• It helps in improving product reliability, safety, and quality.

• DFMEA is a proactive approach to address potential issues befo...read more

Angle of projection is the angle at which an object is projected from the horizontal.

• Angle of projection is measured from the horizontal axis.

• It determines the trajectory of the object being projected.

• A smaller angle of projection results in a shorter range but higher height, while a larger angle results in a longer range but lower height.

• For example, in sports like basketball, the angle of projection of a shot can affect whether it goes in the hoop or not.

Capacitor is used to reduce noise and improve the response time of photo diode.

• Capacitor helps in filtering out high-frequency noise from the output signal of photo diode.

• It also helps in improving the response time of the photo diode by reducing the effect of capacitance in the circuit.

• The value of the capacitor used depends on the frequency of the noise and the response time required.

• For example, in a photodetector circuit, a capacitor of 0.1uF can be used to reduce noise a...read more
