Panchal Machinery Interview Questions and Answers

Current is the flow of electric charge in a circuit.

• Current is measured in Amperes (A).

• It is the rate of flow of electric charge through a conductor.

• Current can be either direct current (DC) or alternating current (AC).

Voltage is the difference in electric potential between two points in a circuit, measured in volts.

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

• It is measured in volts (V)

• Voltage is the potential difference between two points in a circuit

• Higher voltage means more potential energy available to move electrons

• Examples: 120V in household outlets, 12V in car batteries

Material properties refer to the physical and chemical characteristics of a substance.

• Material properties include mechanical properties (e.g. strength, hardness), thermal properties (e.g. conductivity, expansion), electrical properties (e.g. resistivity, conductivity), and chemical properties (e.g. reactivity, corrosion resistance).

• Mechanical properties describe how a material responds to applied forces, such as tensil...read more

Strength of materials is a branch of engineering that deals with the behavior of solid objects subjected to stresses and strains.

• Strength of materials is concerned with the study of how materials deform and fail under various loads.

• It involves analyzing the mechanical properties of materials such as stress, strain, elasticity, and plasticity.

• Understanding the strength of materials is crucial in designing and constructi...read more

DFMEA stands for Design Failure Mode and Effects Analysis, while DFMA stands for Design for Manufacturability and Assembly.

• DFMEA is a systematic approach to identifying and preventing potential failure modes in a design.

• DFMEA involves analyzing each component of a design to determine potential failure modes, their effects, and the likelihood of occurrence.

• DFMA focuses on designing products that are easy to manufacture ...read more

Design procedures are systematic steps followed to create a product or system.

• Design procedures involve defining requirements and constraints.

• They include brainstorming, concept development, prototyping, testing, and refining.

• Documentation of the design process is essential for future reference.

• Examples include the design procedures followed in creating a new software application or a mechanical device.
