Where we can apply Bernoulli equation?
Where we can apply Bernoulli equation? Along a Streamline – Bernoulli’s equation can only be used along a streamline, meaning only between points on the SAME streamline. mixed jets, pumps, motors, and other areas where the fluid is turbulent or mixing. Why do we use Bernoulli equation? The Bernoulli equation is an important expression relating […]
What is edge dislocation and screw dislocation?
What is edge dislocation and screw dislocation? An edge dislocation therefore moves in the direction of the Burgers vector, whereas a screw dislocation moves in a direction perpendicular to the Burgers vector. The screw dislocation ‘unzips’ the lattice as it moves through it, creating a ‘screw’ or helical arrangement of atoms around the core. Is […]

What does a high glass transition temperature mean?
What does a high glass transition temperature mean? The glass transition temperature is the temperature below which the physical properties of plastics change in a manner similar to those of a glassy or crystalline state, and above which they behave like rubbery materials. What will happen when glass transition temperature increases? Usually the most important […]
When a circular shaft is subjected to torque the torsional shear stress is?
When a circular shaft is subjected to torque the torsional shear stress is? Explanation: Shear stress is produced when the shaft is subjected to pure twisting (torsion). The shear stress due to twisting moment is zero at the axis of the shaft. How do you calculate maximum shear stress in a shaft? Shear Stress in […]
