Radiant Design(Rdes Engineering Private Limited) Design Engineer Interview Questions and Answers

Q1. How tensile force act on bolt?
Ans. 
Tensile force acts on a bolt by pulling it in opposite directions, causing it to stretch and potentially fail.
• Tensile force is applied to the bolt in opposite directions, pulling it apart.

• The bolt stretches as the tensile force increases, eventually reaching its breaking point.

• Properly tightening the bolt can help prevent failure due to tensile force.

• Examples: When a heavy load is suspended from a bolt, the tensile for...read more

Add your answer
Q2. How servo motor works
Ans. 
A servo motor is a rotary actuator that allows for precise control of angular position, velocity, and acceleration.
• Servo motors use feedback control to maintain a desired position or speed

• They typically have a DC motor, a gearbox, and a control circuit

• The control circuit sends a signal to the motor to adjust its position based on feedback from a sensor

• They are commonly used in robotics, CNC machines, and automation sys

Q1. What's stress and strain?
Ans. 
Stress is the force applied to a material, while strain is the resulting deformation or change in shape.
• Stress is the internal resistance of a material to deformation under an applied force.

• Strain is the measure of deformation or change in shape of a material in response to stress.

• Stress is typically measured in units of force per unit area (such as Pascals), while strain is dimensionless.

• The relationship between stres...read more

Q2. What is chocking?
Ans. 
Chocking is a condition where a fluid flow is restricted or blocked due to an obstruction in a pipe or duct.
• Chocking can occur in various systems such as hydraulic systems, pneumatic systems, and ventilation systems.

• It can lead to pressure build-up, flow restriction, and potential damage to the system.

• Examples include a clogged pipe causing water flow restriction or a blocked air duct affecting ventilation.

• Chocking can...read more

Q3. What is the pressure ratio for chocking condition?
Ans. 
Pressure ratio for chocking condition is the critical pressure ratio at which the flow of a fluid becomes choked.
• The pressure ratio for chocking condition is the ratio of the outlet pressure to the inlet pressure at which the flow becomes choked.

• It is a critical parameter in the design of nozzles, valves, and other flow control devices.

• For air flowing through a nozzle, the pressure ratio for chocking condition is appro

Q4. If there are two pipes of 8 mm and 10mm diameter,former carrying Helium and later carrying Nitrogen. Which pipe will have higher mass flow rate and which will have higher volume flow rate? Why
Ans. 
The pipe with 10mm diameter carrying Nitrogen will have higher mass flow rate due to higher density. The pipe with 8mm diameter carrying Helium will have higher volume flow rate due to lower density.
• Nitrogen has a higher density than Helium, so the pipe with 10mm diameter will have higher mass flow rate

• Helium has a lower density than Nitrogen, so the pipe with 8mm diameter will have higher volume flow rate

Q5. If three pipes of diameters 4mm 5mm and 8mm are having water flow through them, which pipe can fill a tank faster, considering highest flow rate for the lowest diameter?
Ans. 
The pipe with the highest flow rate for the lowest diameter (4mm) will fill the tank fastest.
• The pipe with the smallest diameter (4mm) will have the highest flow rate for water flow.

• Smaller diameter pipes have higher flow rates due to higher velocity of water flow.

• Therefore, the 4mm diameter pipe will fill the tank fastest compared to the 5mm and 8mm diameter pipes.

Design a pneumatic actuated stage separation mechanism which will have 6 actuators and should work within a time frame of 200ms. The differential delay between the Mechanisms should be 100ms. The delay for valve actuation is 6ms. Design the above system in MATLAB or any preferred code and send the Pressure vs Time plot, relative velocity vs time plot (after stage separation)
