What results from the presence of an extra half plane of atoms in a crystal? Some atomic lattice distortion exists around the dislocation line because of the presence of the extra half-plane of atoms. There are regions in which compressive, tensile and shear lattice strains are imposed on the neighboring atoms. Two edge dislocations that […]
What does a wind tunnel measure?
What does a wind tunnel measure? In wind engineering, wind tunnel tests are used to measure the velocity around, and forces or pressures upon structures. What does pressure coefficient mean? The pressure coefficient is a dimensionless number which describes the relative pressures throughout a flow field in fluid dynamics. The pressure coefficient is used in […]

Vinyl Siding Can Result in Other Maintenance Issues. Vinyl Siding May Lower Your Home’s Value. Vinyl Siding May Permit Moisture Below the Surface. What […]
How many seconds should you signal before turning or changing lanes?
How many seconds should you signal before turning or changing lanes? five seconds When changing lanes you should remember that? When changing lanes, the most important thing is to wait until there is a clear gap in the traffic. Then move safely and smoothly into the center of the desired lane, while maintaining your space […]
What is the difference between phase angle and phase difference?
What is the difference between phase angle and phase difference? Definition: The phase difference between the two electrical quantities is defined as the angular phase difference between the maximum possible value of the two alternating quantities having the same frequency. The angle between zero points of two alternating quantities is called angle of phase differences. […]
Is quicksort recursive?
Is quicksort recursive? Overview of quicksort. Like merge sort, quicksort uses divide-and-conquer, and so it’s a recursive algorithm. The way that quicksort uses divide-and-conquer is a little different from how merge sort does. In merge sort, the divide step does hardly anything, and all the real work happens in the combine step. What is recursive […]
What is the fluid power industry?
What is the fluid power industry? Fluid power is the use of fluids under pressure to generate, control, and transmit power. Compressed-air and water-pressure systems were once used to transmit power from a central source to industrial users over extended geographic areas; fluid power systems today are usually within a single building or mobile machine. […]
What does criteria and constraint mean?
What does criteria and constraint mean? Criteria are rules or directions that must be followed; they are the requirements that must be met. • Constraints are restrictions that keep something. from being the best that it can be. They can be. problems that arise or issues that come up. What is the purpose of criteria […]
What is the deepest part of the Challenger Deep?
What is the deepest part of the Challenger Deep? The Challenger Deep in the Mariana Trench is the deepest known point in Earth’s oceans. In 2010 the United States Center for Coastal & Ocean Mapping measured the depth of the Challenger Deep at 10,994 meters (36,070 feet) below sea level with an estimated vertical accuracy […]
What are the limitations of investment casting?
What are the limitations of investment casting? Disadvantages It can be difficult to cast objects requiring cores. This process is expensive, is usually limited to small casting, and presents some difficulties where cores are involved. Holes cannot be smaller than 1/16 in. Investment castings require longer production cycles compared to other casting processes. What is […]
