## What is catenary and write its types?

The catenary is also called the alysoid, chainette, or, particularly in the materials sciences, funicular. Rope statics describes catenaries in a classic statics problem involving a hanging rope. Mathematically, the catenary curve is the graph of the hyperbolic cosine function.

**What is catenary function?**

catenary, in mathematics, a curve that describes the shape of a flexible hanging chain or cable—the name derives from the Latin catenaria (“chain”). Any freely hanging cable or string assumes this shape, also called a chainette, if the body is of uniform mass per unit of length and is acted upon solely by gravity.

### What is a catenary function?

**How does the catenary curve work?**

## What is catenary shape?

**What is catenary solution?**

The solution of the catenary problem provides the starting point for consideration of the effects on a suspended cable of extraneous applied forces such as arising from the live loads on a practical suspension bridge.

### What is catenary physics?

If a flexible chain or rope is loosely hung between two fixed points, it hangs in a curve that looks a little like a parabola, but in fact is not quite a parabola; it is a curve called a catenary, which is a word derived from the Latin catena, a chain.

**How is brachistochrone calculated?**

In other words, the brachistochrone curve is independent of the weight of the marble. Since we use the interpolation function int1 to approximate the curve , we can define a global variable T for the travel time using the formula given above: integrate(sqrt((1+(d(int1(x),x))^2)/max(0-int1(x),eps)),x,0,xB) .

## How did Bernoulli solve the Brachistochrone problem?

In Bernoulli’s brachistochrone problem one has two points at different elevations and one seeks the minimum-time curve for a particle to slide frictionlessly from the higher point to the lower point. The well known answer to the Bernoulli problem is the unique cycloid extending from the higher point to the lower point.

**What is the difference between parabola and catenary?**

A catenary cable sags under such a uniformly distributed load along its length, and transfers the load to its two supports in equal shares. In contrast, a parabola is a funicular shape of a suspension cable loaded uniformly across its span.

### Is a catenary a parabola?

The Catenary and the Parabola Conceptually The shape of a catenary resembles greatly the shape of a parabola. In fact, in general the visual difference between these two curves is almost imperceptible. However, there is a clear conceptual as well as mathematical difference between these two curves.

**What is meant by brachistochrone?**

Definition of brachistochrone : a curve in which a body starting from a point and acted on by an external force will reach another point in a shorter time than by any other path.

## Why is brachistochrone the fastest?

The brachistochrone problem is one that revolves around finding a curve that joins two points A and B that are at different elevations, such that B is not directly below A, so that dropping a marble under the influence of a uniform gravitational field along this path will reach B in the quickest time possible.
