Bi-axial symmetry refers to an object or organism that can be divided into two equal halves in two different ways, resulting in two possible lines of symmetry. This characteristic is commonly found in certain crystals and some sea creatures.
Biaxial joints allow for movement in two planes or axes. A common example of a biaxial joint is the wrist, which allow for movement side to side, and also allows for movement up and down. It can be difficult to determine whether a joint is biaxial or multiaxial, because when the biaxial joint moves in both directions at the same time, it appears to have the multiaxial quality of being able to move in any plane or axes.
Biaxial loading refers to the application of two perpendicular (often mutually orthogonal) loads or stresses on a material or structure simultaneously. This type of loading can lead to more complex deformation patterns compared to uniaxial loading. It is commonly encountered in engineering applications where materials are subjected to multi-axial stress states.
The ankle joint is primarily considered a uniaxial joint, as it mainly allows movement in one plane—dorsiflexion and plantarflexion. However, it does have some limited biaxial characteristics due to the subtalar and other surrounding joints, which permit slight inversion and eversion. Overall, the ankle's primary function is in one axis of movement.
Arial symmetry
Yes, it is possible to have a shape that has a line of symmetry but does not have rotational symmetry. An example is the letter "K", which has a vertical line of symmetry but cannot be rotated to match its original orientation.
yes
Uniaxial crystals have one optic axis, where the refractive index is the same in all directions perpendicular to it. Biaxial crystals have two optic axes, with different refractive indices along each direction. This causes different light paths and behaviors in biaxial crystals compared to uniaxial ones.
Yes
Biaxial joints allow for movement in two planes or axes. A common example of a biaxial joint is the wrist, which allow for movement side to side, and also allows for movement up and down. It can be difficult to determine whether a joint is biaxial or multiaxial, because when the biaxial joint moves in both directions at the same time, it appears to have the multiaxial quality of being able to move in any plane or axes.
yes
There are two types uniaxial or biaxial.
Biaxial cable consists of two side-by-side coaxial cables held together by an outer insulating jacket.
yes
No, a pivot joint and a biaxial joint are not the same. A pivot joint allows only rotating movement around one axis, like the movement of the head from side to side. A biaxial joint allows movement in two perpendicular axes, such as the wrist which can move up and down as well as side to side.
A bisectrix is the line bisecting the angle between the optic axes of a biaxial crystal.
That is stress in three dimensions. Biaxial stress is in two dimensions. Triaxial stress has normal and shear stresses along each of three planes. Most beams can be analyzed with uniaxial stress; plates with biaxial; solids with triaxial
The wrist joint is primarily considered a biaxial joint. It allows movement in two planes: flexion and extension (sagittal plane) as well as radial and ulnar deviation (frontal plane). However, the wrist also facilitates some degree of rotation due to the complex interactions of the carpal bones, which can lead to some multiaxial characteristics. Overall, its primary classification remains biaxial.
