In a system, damping explains how quickly the system will return to a state of rest after some external force has acted upon it. For example, in control systems, the goal is often to stop a system from spinning or vibrating. The damping ratio expresses that response as a ratio between the actual damping of …
Thermal diffusivity is the measure of how fast heat spreads through a given material. It is essentially how fast and effectively a material can conduct heat after considering the stored heat. There are a few ways to describe thermal diffusivity, so let’s get into them. Table of ContentsWhat Does Thermal Diffusivity Tell Us?What Does Thermal …
Torsional rigidity is defined as how much an object of specified material resists twisting force, also known as torque. It is based on both the material of the object, as well as its shape. Table of ContentsWhat Is Torsional Rigidity?How is Torsional Rigidity Measured?Torsional Rigidity vs Lateral RigidityWhy Is Torsional Rigidity Important?How Do You Increase …
Fluid pressure and flow rate are important considerations when designing a pipe system. In ideal circumstances, there would be no loss of energy within the system to affect the pressure and flow rate. However, in real applications engineers must consider energy lost due to frictional resistance, which is typically referred to as “head loss.” To …
The Bernoulli Equation is one of fluid mechanic’s classic equations, used for hundreds of years to calculate idealized flows. The equation is essentially an application of the law of conservation of energy, used to track pressure and flow changes. However, because of the viscous, unsteady, and irreversible nature of turbulent flows, Bernoulli’s equation is largely …

A moment is the force that tries to pull on a beam or other object to rotate it. A moment connection is a type of joint that acts to prevent this turning force, transferring the energy away and keeping two beams solidly in place. Table of ContentsWhat is a Beam To Beam Moment Connection?Types of …
If a bolt is being used to assemble two plates, this could be achieved by either putting clearance holes in both plates and using a nut on the opposite end, or by putting a clearance hole in the first plate and a tapped hole in the second plate. Either way, one of the assembled objects …
