Pebs Pennar Design Engineer Interview Questions and Answers

Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy.

• It studies the transfer of energy in the form of heat and work.

• It involves concepts like temperature, pressure, and entropy.

• Examples include the efficiency of engines and refrigerators based on thermodynamic principles.

Torque is a twisting force that causes rotation, while bending moment is a force that causes an object to bend.

• Torque is a rotational force applied to an object, typically measured in Newton-meters (Nm)

• Bending moment is a force that causes an object to bend or flex, typically measured in Newton-meters (Nm)

• Torque is commonly seen in applications like tightening bolts or rotating machinery

• Bending moment is often encounte...read more

A control module is a device that manages and regulates the operation of a system, while a relay module is a device that controls the flow of electrical current.

• Control modules are responsible for monitoring and adjusting various parameters in a system, such as temperature, pressure, or speed.

• Relay modules act as switches that open or close circuits to control the flow of electrical current.

• Control modules are typicall...read more

The system architecture of FAS (Fire Alarm System) and BMS (Building Management System) involves the integration of various components and subsystems to ensure efficient monitoring and control of fire safety and building operations.

• FAS system architecture typically includes fire detectors, control panels, notification devices, and communication interfaces.

• BMS system architecture typically includes sensors, controllers,...read more
