There are several types of dampings in case of vibration, including viscous damping, hysteretic damping, and structural damping.

• Viscous damping: It occurs when a fluid or viscous material is used to dissipate energy and reduce vibration.

• Hysteretic damping: It is caused by the internal friction within a material, which converts mechanical energy into heat.

• Structural damping: It is inherent in the structure itself and is...read more

Newtonian fluid is a type of fluid that follows Newton's law of viscosity.

• Newtonian fluid exhibits a linear relationship between shear stress and shear rate.

• Examples of Newtonian fluids include water, air, and most oils.

• Stages of fracture include initiation, propagation, and final failure.

• Engine works by converting heat energy into mechanical work.

• Basic thermodynamics questions may include concepts like the first and s...read more
