Celestial navigation is available to Inuit travellers, although the time that navigation technique is available is limited by the variability of night-time through the year and other factors. [3] Cloudy and blizzard conditions and the light of the aurora borealis limit its use. [4] Snow that was kept airborne by the wind, created a type of fog.
The bottom of the two-story g is a loop; the very short stroke at the top is the ear. [10] The letters i j each have a dot or tittle. [10] A short horizontal stroke, as in the center of e f and the middle stroke of E F, is a bar. Strokes that connect, as in A and H, or cross other strokes, as in t, are also known as crossbars. [9]
For standardized testing of fracture toughness by the Charpy impact method, specimen and notch dimensions are most often taken from American standard ASTM E23, or British standard BS EN ISO 148-1:2009. For all notch types, a key parameter in governing stress concentration and failure in notched materials is the notch tip curvature or radius. [1]
Bicycle frame in steel tube, notched at the joints before TIG welding or brazing. Tube notching is commonly performed before joining light-gauge tubes to make a tee or similar joint, as by welding. Either one or both tubes may be notched before assembly. A familiar example of tube notching is in the manufacture of bicycle frames.
In a three-point bend test, a fatigue crack is created at the tip of the notch by cyclic loading. The length of the crack is measured. The specimen is then loaded monotonically. A plot of the load versus the crack opening displacement is used to determine the load at which the crack starts growing.
A birds-mouth joint in a rafter, set upon a double top plate. Shown are the two cuts of the joint: the seat cut and the heel cut. In light frame construction, a birdsmouth joint or bird's beak cut is a woodworking joint that is generally used to connect a roof rafter to the top plate of a supporting wall. [1]
Where p is a proton, n is a neutron, e + is a positron, e-is an electron, and ν indicates a neutrino (or an antineutrino if there's a bar over it). Hope that helps; if you have more questions, ask them. -- SCZenz 03:51, 1 December 2005 (UTC)
Drawing up a comprehensive list of words in English is important as a reference when learning a language as it will show the equivalent words you need to learn in the other language to achieve fluency.
