The Catenary and Parabola are different curves that look similar; they are both "U" shaped and symmetrical, increasing infinitely on both sides to a minimum.

How are the catenary arch and parabolic arch different?

A catenary is produced by hanging a chain from two points some distance apart. The equation for a catenary is the hyperbolic cosine. One simple example of a catenary can be found if you look at the power lines running between two poles. A parabola is produced by putting a hanging chain or cable under an equally dispersed load. An example of this can be seen on a suspension bridge, the cable hanging from two towers with the road below hanging from vertical cables attached to the main suspension cables.


What is the midpoint of the parabola between the focus and the directrix?

It is the apex of the parabola.


What is catenary towing?

A catenary is the curve formed by slack wire - telephone cables are a good example. So a catenary tow is one where, simply put, the towline is attached to shackles of anchor cable in order to ensure that a belly of towline (providing spring) hangs between the two ships.


What is the extreme point of a parabola that is located halfway between the focus and directrix called?

It is the vertex of the parabola.


What is the difference between a Parabola and a Trajectory?

Trajectory is the path a projectile follows Parabola is the shape of this path


What is the strength of the quaternary?

In physics and geometry, the catenary is the theoretical shape a hanging chain or cable will assume when supported at its ends and acted on only by its own weight. The curve is a hyperbolic cosine which has a U-like shape, similar in appearance to a parabola.


What is the difference between hyperbola and parabola?

A parabola has eccentricity 1, a hyperbola has eccentricity greater than 1.


What is catenary taping?

Catenary taping is where tape measurements are mage above the ground suspended between tripod. corrections have to be made for the sag of the tape from the horizontal. Using this method makes measuring over uneven ground easier.


What is the difference between a cubic and a parabola and line?

A cubic line is in a cube shape line. and Parabola is a straight line


What is a kind of bridge that hangs from cables?

A cable suspension bridge is a kind of bridge hung from cables.


The is the extreme point of a parabola and is located halfway between the focus and directrix?

The vertex -- the closest point on the parabola to the directrix.


The is the extreme point of a parabola and is located halfway between the focus and directrix.?

This extreme point on the parabola is called the vertex. In math. a parabola is a U-shaped curve with a directrix, which is a fixed straight line.
