Q1. What is Bernoulli principle?
Ans. 
Bernoulli principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.
• States that as the speed of a fluid increases, its pressure decreases

• Used to explain lift in airplane wings

• Applies to various fluid dynamics situations such as flow through pipes

Q2. What is stress and how it can be measured?
Ans. 
Stress is a force acting on a material that causes deformation. It can be measured using techniques like strain gauges and load cells.
• Stress is a measure of the internal forces within a material resisting deformation.

• It is typically measured in units of force per unit area, such as Pascals or pounds per square inch.

• Common methods of measuring stress include strain gauges, load cells, and extensometers.

• Stress can be cat...read more

Q2. Explain the tool used Boundary conditions Degree of freedom Next higher level situation (assembly constraints)
Ans. 
Boundary conditions, degree of freedom, and assembly constraints are tools used in design engineering to define and analyze the behavior of a system.
• Boundary conditions are constraints that define the limits of a system's behavior or performance.

• Degree of freedom refers to the number of independent parameters that can be varied without violating the constraints of the system.

• Assembly constraints are the restrictions pl...read more

Q1. Under which stress spring fails?
Ans. 
A spring fails under stress beyond its elastic limit.
• A spring fails when it is subjected to stress beyond its elastic limit.

• The elastic limit is the maximum stress a spring can withstand without permanent deformation.

• Factors affecting the failure of a spring include material properties, design, and operating conditions.

• Examples of spring failure include fracture, fatigue, and creep.

• Fracture occurs when the spring is su...read more

Q2. What is synchronous speed of motor?
Ans. 
Synchronous speed of a motor is the speed at which the rotating magnetic field produced by the stator rotates.
• It is determined by the number of poles and frequency of the power supply.

• It is the speed at which the motor would run if there was no load or slip.

• It is expressed in revolutions per minute (RPM).
