During deep drawing operation , edges of the blank lifts up and wrinkles are formed due to circumferential compressive stress
Within elastic limit, the force required to stretch an elastic object (stress) such as a metal spring is directly proportional to the extension of the spring(strain) . This is known as Hooke’s law
Twist drill can only cut in axial direction
The specific weight (also known as the unit weight) is the weight per unit volume of a material
Bernoulli’s principle states, ” For a perfect incompressible liquid, flowing in a continuous stream, the total energy of a particle remains the same, while the particle moves from one point to another.”
Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities, which is known as a boundary layer in the case of a bounding surface such as the interior of a pipe.
Manometric head is measured across the pump inlet and outlet flanges.
Servo motor helps in precise control of angular or linear position, velocity and acceleration.
The lag compensator reduces the gain of the system and adds phase lag.
The lead compensator increases bandwidth and phase shift.
