Roundness is dominated by the shape's gross features rather than the definition of its edges and corners, or the surface roughness of a manufactured object. A smooth ellipse can have low roundness, if its eccentricity is large. Regular polygons increase their roundness with increasing numbers of sides, even though they are still sharp-edged.
Find which legs are in stance and the location of the center of mass. Note, if there are less than 3 legs in stance then the animal is not statically stable. Form the support polygon by creating edges between these legs in a clock-wise manner. Determine if the center of mass lies inside or outside of the support polygon.
Slope stability refers to the condition of inclined soil or rock slopes to withstand or undergo movement; the opposite condition is called slope instability or slope failure. The stability condition of slopes is a subject of study and research in soil mechanics , geotechnical engineering , and engineering geology .

The roundness or sharpness of handwriting patterns is caused by the phase of the horizontal and vertical pen-tip movements. The velocity signal components of these movements, which are virtually sinusoidal in shape, have a phase delay close to 90 degrees for very round handwriting.
Defined by Wadell in 1935, [1] the sphericity, , of an object is the ratio of the surface area of a sphere with the same volume to the object's surface area: = where is volume of the object and is the surface area.
The movement of each of the components of the Boulton & Watt Steam Engine (1784) is modeled by a continuous set of rigid displacements. The position of one component of a mechanical system relative to another is defined by introducing a reference frame, say M , on one that moves relative to a fixed frame, F, on the other.
Body roundness index takes into account a person's height and waist circumference to determine whether they are in a healthy or unhealthy sphere, according to Maya Feller, a registered dietitian ...
