What is a traction boundary condition? Traction free boundary condition means that the the surface is free from external stress. We can mathematically express this as > t = σ.n = 0. where, t is the surface traction in the current configuration; σ = Cauchy stress tensor; n = vector normal to the deformed surface. […]
How long will it take an S-wave to travel 4000 km?
How long will it take an S-wave to travel 4000 km? The graph shows that the S-waves need about 12 minutes: 40 seconds to travel the same distance. Therefore, if the time separation between the arrival time of the P- and S-waves is 5 minutes:40 seconds, the epicenter must be 4000 km away. How long […]
Is table salt in water a colloid suspension or true solution?
Where is nuclear waste currently stored?
Where is nuclear waste currently stored? Level Nuclear Waste SNF is stored in one of two ways: in wet storage pools and in dry casks. Immediately following power production, SNF is discharged from the reactors and stored in wet storage pools on site, as it remains intensely radioactive and thermally hot. Why dont we throw […]
What is data classification and why is it important?
What is data classification and why is it important? Data classification helps organizations answer important questions about their data that inform how they mitigate risk and manage data governance policies. It can tell you where you are storing your most important data or what kinds of sensitive data your users create most often. What are […]
What are two kinds of reflection?
What are two kinds of reflection? The reflection of light can be roughly categorized into two types of reflection. Specular reflection is defined as light reflected from a smooth surface at a definite angle, whereas diffuse reflection is produced by rough surfaces that tend to reflect light in all directions (as illustrated in Figure 3). […]
What is the 11 year sun cycle?
What is the 11 year sun cycle? The Short Answer: The Sun’s magnetic field goes through a cycle, called the solar cycle. Every 11 years or so, the Sun’s magnetic field completely flips. This means that the Sun’s north and south poles switch places. Then it takes about another 11 years for the Sun’s north […]
How much clearance do you need in front of disconnect?
How much clearance do you need in front of disconnect? The minimum working space height required for the disconnect switch is 61/2 feet (see Figure 6). The minimum working space height for electrical equipment has not always been 61/2 feet. For many years, the working space height (or headroom) was required to be at least […]
