- Katanas are curved because, when forging, the side of the edge is being squished, and the metal is being squished away from that point, thus bending the sword. kenno99999 July 12th, 2017

Aeolian processes Wind-driven grains abrade landforms. Grinding by particles carried in the wind creates grooves or small depressions. Ventifacts are rocks which have been cut, and sometimes polished, by the abrasive action of wind.Sculpted landforms, called yardangs, are up to tens of meters high and kilometers long and are forms that have been streamlined by desert winds. The famous sphinx at Giza in Egypt may be a modified yardang.entifacts are rocks which have been cut, and sometimes polished, by the abrasive action of wind.

Bowstring Trusses âFailâ to Meet Current Code Requirements Bowstring trusses are made with a curved top chord and a straight bottom chord. The top chords were originally made with multiple leaf chords where the curvature was cut into the solid sawn chord members.A second style of bowstring truss used glued-laminated chords. The top chord in these trusses was curved in the laminating process.While these trusses have carried the roof load for decades, it is not uncommon to receive calls regarding broken trusses following a heavy snow event.he top chords were originally made with multiple leaf chords where the curvature was cut into the solid sawn chord members.

What are the reasons that flight paths (especially for long haul flights) are seen as curves rather than straight lines on a screen? Is map distortion the only reason? Or do flight paths consider the rotation of the Earth? They appear curved on the screen because the screen is flat and the Earth isn't. Assuming no flight restrictions, use a string to connect two points on a globe and you will have your straight path. Mark all the cities you would fly over and then move to a flat map of the world.

- When a curvature, or scoliosis, is mild then one may not be able to detect any abnormality without an X-ray. On the other hand, moderate or severe scoliosis can be noted due to an asymmetry of the back. A tilted waistline and skin folds may be present, as well as a hunching, or protrusion of the back.hen a curvature, or scoliosis, is mild then one may not be able to detect any abnormality without an X-ray.

- Kyphosis, also known as a round back or hunchback, is a condition in which the spine in the upper back has an excessive curvature. The upper back, or thoracic region of the spine, is supposed to have a slight natural curve.The spine naturally curves in the neck, upper back, and lower back to help absorb shock and support the weight of the head. Kyphosis occurs when this natural arch is larger than normal.If you have kyphosis, you may have a visible hump on your upper back. From the side, your upper back may be noticeably rounded or protruding. In addition, people with hunchback appear to be slouching and have noticeable rounding of the shoulders.yphosis caused by poor posture is called postural kyphosis. Other potential causes of kyphosis include: 1  aging (especially if you have poor posture). 2  muscle weakness in the upper back. 3  Scheuermann’s disease (occurs in children and has no known cause).

Flexible Curves These flexible curves will mold to radii as small as 1/2 without kinking. Each has a square lead core with spring steel on two sides to let you easily copy any curve. The spring steel sides keep curves smooth and help keep the curve in one plane so that it will lie flat for tracing. These are dead curves that hold a shape well without spring-back. The vinyl covering has a slightly raised bead on one side for inking and a flat bead on the other for a pencil. Each is an excellent tool for laying out smooth curves for tracing, or for copying existing curves such as the compound curve of a rocker.

Scoliosis  In-Depth Report 1 Structural scoliosis: In addition to the spine curving from side to side, the vertebrae rotate, twisting the spine. 2  As it twists, one side of the rib cage is pushed outward so that the spaces between the ribs widen and the shoulder blade protrudes (producing a rib-cage deformity, or hump).coliosis is often categorized by the shape of the curve, usually as either structural or nonstructural. 1  Structural scoliosis: In addition to the spine curving from side to side, the vertebrae rotate, twisting the spine. 2  Nonstructural scoliosis: The curve does not twist but is a simple side-to-side curve.
