Viruses have different geometrical shapes, such as helical and polyhedral shapes. A particular polyhedral shape common to many viruses is a dodecahedron shape. This is a geometric shape that has 12 sides.
Yes, a screw is a helical inclined plane.
If you mean find the helical angle, alpha, using the pitch, p, with a shaft of radius, R, at the root of the teeth then: alpha= arctan( p /(2R) ) Otherwise, if you mean find the helical angle while designing a gear, it is quite complicated and requires the knowledge of various parameters such as the maximal torque, speed, material, etc.
How do calculate spiral length of Spiral rings
Viruses have four main shapes: 1. spherical (like a ball) 2. helical (like a corkscrew or a spring) 3. Icosahedron (a twenty-sided shape kind of like two prisms glued together) 4. Bacteriophage (an icosahedron head and a spider-like tail)
When one uses the term "helical", one is often referring to the shape of a helix or spiral. An object with a spiral or helical shape, is one that has a shape or form similar to the helix.
Protein is a chemical family name. Its shape may be helical. But a helical shape is of a spring type item shape.
The three types of capsid are helical, icosahedral, and complex. Helical capsids have a cylindrical shape, icosahedral capsids have a polyhedral shape with 20 equilateral triangular faces, and complex capsids have a combination of both helical and icosahedral elements.
The helical shape of a bi-metallic thermometer helps to amplify the movement of the jointed bi-metallic strip when temperature changes occur. This allows for a more accurate and visible indication of temperature fluctuations by increasing the sensitivity of the thermometer. Additionally, the helical shape provides support and protection to the delicate mechanism inside the thermometer.
The helical virus is a type of virus that has a capsid structure in the shape of a helix. This helical structure is formed by protein subunits arranged in a spiral around the viral genetic material. Examples of helical viruses include tobacco mosaic virus and influenza virus.
DNA is double helical (like a step ladder) in structure
Helical viruses have a rod-like shape with a helical symmetry, such as the tobacco mosaic virus, while icosahedral viruses have a polyhedral shape made up of 20 equilateral triangular faces, like adenoviruses. Diseases caused by helical viruses include Ebola and influenza, while diseases caused by icosahedral viruses include the common cold and polio.
Cellulose molecules have a linear shape, with a repeating chain of glucose units bonded together.
A virus can have one of two structures. These are: •Helical virus. A helical virus is rod- or thread-shaped. The virus that causes rabies is a helical virus. •Icosahedral virus. An icosahedral virus is spherically shaped. Viruses that cause poliomyelitis and herpes simplex are icosahedral viruses.
Coccus(Round shape), Bacillus(Rod shape), Spiral bacteria(Motile bacteria having a helical or spiral shape) By Arcangel Meynard
Viruses have different geometrical shapes, such as helical and polyhedral shapes. A particular polyhedral shape common to many viruses is a dodecahedron shape. This is a geometric shape that has 12 sides.
