If you pull a bar, its diameter will decrease as the bar expands. Strain in the direction of expansion (contraction) is called “longitudinal strain” while the change in the diameter direction (the direction perpendicular to the external force) is called “lateral strain” (εh). ...
Trails appear on a topographic map as thin black lines. Roads will be thicker red or black lines. As you choose your route from Point A to Point B, keep a close eye on your map's contour lines. If the lines are far apart, any changes in elevation will be gradual. If they're clos...
Since the legs of a rectangle are perpendicular, the matrix [uv] is orthogonal and so we even have a simple formula for the inverse: [uv]−1=[uT/||u||2vT/||v||2]. If you want to check many points for the same rectangle, this matrix can be easily precomputed and stored, so ...
A. { a} and { b} are parallel. B. { a} and { b} are not parallel. How to test if a vector is in the span? Determine whether the vectors a = 4 i - 2 j + 6 k and b = 6 i - 3 j + 9 k are parallel, perpendicular, or neither. Determine whether the vectors a = ...
(how sharp the fingerprint scan is). The processor looks at several straight lines moving horizontally and vertically across the image. If the fingerprint image has good definition, a line running perpendicular to the ridges will be made up of alternating sections of very dark pixels and very ...
The processor looks at several straight lines moving horizontally and vertically across the image. If the fingerprint image has good definition, a line running perpendicular to the ridges will be made up of alternating sections of very dark pixels and very light pixels. If the processor finds ...
Fabric suppliers will provide you with two measurement points—if they don’t, ask for it. Two measurements to consider are the total width and the cuttable width. The edges of the fabric can be skewed or damaged during production and transportation, so it’s best to refer to the ...
If it lands behind you throw more perpendicular to the wind.Step 3: Hold the boomerang with your thumb and forefinger. Have the top side (with the top of the airfoil) facing you. It doesn't matter which wing you hold, just chuck it with the top side pointing toward your face. ...
These rays, which are perpendicular to the local wavefront, travel in straight lines through homogenous media. The rays will change direction at refractive boundaries per Snell's Law and reflect at boundaries per the Law of Reflection. They will change direction at diffractive interfaces according ...
Make sure they are parallel to the ground and that the headboard and footboard are perpendicular. Squaring the Corners: Use a carpenter’s square to ensure each corner forms a 90-degree angle. This step is crucial for the bed’s stability and aesthetic appeal. Screwing in Place: Once every...
