What is the zero circle of the Planimeter?

The “Zero Circle” can then be defined as being a line along which the Tracer can be moved without producing any rolling of the Wheel whatever. Fig. 1 of Plate III shows a plan of the Planimeter when the Arms are in position to cause the Tracer to describe the Zero Circle, while Fig.

How do you find the zero of a circle?

Methods for the determination of the area of zero circle (ii) Place the tracing point at T, the anchor point at A and the wheel at W. Measuring the distance AT between the anchor point and the tracing point, which gives the radius R of the zero circle.

How do you type 0?

To generate a slashed zero on typewriters, typists would type a normal “O” or zero, backspace, and then hit the slash key to mark the zero.

What is the difference between O and zero?

A zero (0) is a number which represents “nothing”. An “O” is the capitalised 15th letter of the modern English alphabet. They do look similar, especially in writing.

What is meant by zero circle How is it accounted for in the measurement of areas?

Zero circle or the circle of correction, is the circle around whose circumference if the tracing point is moved but no rotation of the wheel will be caused. the wheel will slide on the paper without causing any change in the reading.

Can a circle have radius 0?

In various high school textbooks, when the radius of a circle is zero, it is said that it is a degenerate circle of zero radius. That means we’re looking at a circumference of zero radius. Consequently, only one point belongs to the circumference, which is the centre.

Is it o or zero?

American speakers use zero in both conversation and writing. When reciting a string of numbers only, it is acceptable and common for an American to pronounce zero as oh . But when reciting a string that mixes characters and numbers, it becomes necessary to differentiate between oh and zero.

How can you tell a zero from an O?

The slashed zero glyph is often used to distinguish the digit “zero” (“0”) from the Latin script letter “O” anywhere that the distinction needs emphasis, particularly in encoding systems, scientific and engineering applications, computer programming (such as software development), and telecommunications.

What does it mean when the radius of a circle is zero?

In various high school textbooks, when the radius of a circle is zero, it is said that it is a degenerate circle of zero radius. That means we’re looking at a circumference of zero radius. Consequently, only one point belongs to the circumference, which is the centre.

What does the line-circle (| o) mean?

Think binary. We were recently in a hotel in Berlin Germany and the room heater had the line-circle (| O) symbol on it and we couldn’t remember whether line means on and circle means off, or the line means off and circle means on. Quality German engineering made the heater silent so there was no way to tell by listening.

What is the set of points of a point circle?

If that fixed distance is zero, then that set of points is simply the center point itself.”, or as I would put it, a point circle is a set containing exactly one point. However, this a mathematical and theoretical construct only. When you talk about “zooming in” you seem to be implying that its a real physical thing that has dimensions.

Is there any other degenerate circle other than this circle?

There’s no other degenerate circle, because there is only one way for circles to become degenerate. (That is, when the radius goes to zero.) However, it’s a special case of a degenerate conic section.
