Boeing Design Engineer Interview Questions, Process, and Tips

Harness is the collection of wires and cables that transmit signals and power between different components in a system.

• Harness is used to organize and protect wires and cables in a system.

• It helps in reducing electromagnetic interference and improving signal integrity.

• Harness can be customized based on the specific requirements of the system.

• Examples include wiring harness in automotive industry and cable harness in ae

Earthing is the process of connecting electrical systems to the ground to prevent electric shock and protect equipment.

• Earthing provides a path for fault currents to flow safely to the ground.

• It helps in stabilizing voltage levels and protecting against lightning strikes.

• Different types of earthing systems include TN-C, TN-S, TT, and IT systems.

• Proper earthing is essential for safety in electrical installations.

Slack in routing refers to the amount of time a task can be delayed without affecting the project schedule.

• Slack allows for flexibility in project timelines

• It is the difference between the earliest and latest start time of a task

• Tasks with zero slack are critical and cannot be delayed

• Slack is calculated using the Critical Path Method (CPM)

• Example: If a task has a duration of 5 days and a slack of 2 days, it can be dela...read more

Branch points are used in fluid mechanics to model the flow of fluids through branching pipes.

• Branch points are used to calculate the pressure and flow rate of fluids at junctions in a pipe system.

• They are commonly used in the design of plumbing and HVAC systems.

• Branch points can also be used to model the flow of blood through arteries and veins in the human body.

• In computational fluid dynamics, branch points are used ...read more

The bend radius in electrical harness refers to the minimum radius that a wire or cable can be bent without causing damage.

• The bend radius is important to ensure the longevity and performance of the electrical harness.

• It is determined by the type and size of the wire or cable being used.

• Smaller bend radii can lead to increased stress on the wire, potentially causing insulation damage or wire breakage.

• The bend radius sh...read more
