what are cylindrical and spherical power?
428707
Spherical power refers to the amount of correction needed for myopia or hyperopia (nearsightedness or farsightedness). Cylinder refers to correction for astigmatism, and both may change over time.

Cylindrical robots are used for assembly operations, handling of machine tools and die-cast machines, and spot welding. With its combined rotational joint, two rotary joints, and a linear joint, the spherical robot operates in the polar coordinate system to achieve a spherical-shaped work envelope.

['Power is defined as the rate of doing work, it is the work done in unit time, and the SI unit is given as watt (W) which is joules per second (J/s).', 'The formula is given by P = V x I.']

You calculate the volume of a cylinder by squaring the radius (r) of its cross-sectional area and multiplying by π and its height (h): V = πr2h.

P = pgh (pressure vs. depth) P=ρgh. P is pressure, ρ is the density of the fluid; g is the gravitational constant, h is the height from the surface, or depth that the object is submerged.

Volume of a sphere. The formula for the volume of a sphere is V = 4/3 πr³. See the formula used in an example where we are given the diameter of the sphere.

First, divide the diameter by 2 and plug the values for volume, pi, and radius into the formula for volume of a cylinder. Next, square the radius and multiply the values together. Then, divide both sides by 200.96 for the answer, remembering to include the appropriate unit of measurement.

The formula is π(r^2)*h, with r being the radius and h being the height. So the relationship between the radius and volume would be that the volume of a cylinder is the radius squared and multiplied by π and h.

Men Spherical Candle, power(M.S.C.P): The intensity of illumination from a lamp varies in different directions. M.S.C.P. is the average value in all directions. ... The average candle-power of a light source in all direction in a plane through the centre of the source and perpendicular to its axis.

Cylinder volume & surface area. A cylinder's volume is π r² h, and its surface area is 2π r h + 2π r².

A glasses prescription contains a sphere indicating the lens power, a cylinder indicating strength of any astigmatism (if there is one stated) and an axis showing the orientation of the cylinder. ... You'll find that the cylinder number on a contact lens prescription is always a minus number.

Note : The volume of a sphere is 2/3 of the volume of a cylinder with same radius, and height equal to the diameter.

Circles have area. Spheres have volume. The area of a circle with a radius of r is π * r^2, and the volume of a sphere with a radius of r is (4/3) * π * r^3.

The term "sphere" means that the correction for nearsightedness or farsightedness is "spherical," or equal in all meridians of the eye. Cylinder (CYL). This indicates the amount of lens power for astigmatism. ... Cylinder power always follows the sphere power in an eyeglass prescription.

The lateral surface area of a sphere is given by 4\pi r^{2} where r is the radius of the sphere. Hence, the Curved Surface Area (CSA) of a Hemisphere is given by 2\pi r^{2} where r is the radius of the sphere of which the hemisphere is a part. The total surface area (TSA) of a Hemisphere is given by 3πr2.
