- ‘Now, the principle for doing that is demonstrated by the catenary principle, otherwise known as the principle of least action; that is, Leibniz's principle of least action.’

- ‘Turning the curve upside down gives you an inverted catenary.’
- ‘Like the tardigrade, this earthquake-resistant house is all curves, from the oval floor plan to the dual parabolic and catenary arches of its profile.’
- ‘While others in the profession worked with straight edges, Gaudi invented his own methods for modeling parabolic arches from the catenary curve created by suspending a length of chain between two points.’
- ‘The tapes needed to be checked on a flat surface because holding them in suspension would produce a catenary which would make it difficult to check the correctness of the measurement.’
- ‘The roof is made in a similar way to the walls, with the cables allowed to adopt a catenary curve between the core and the outer steel compression ring.’
- ‘The tube is not stretched tight, but hangs like a chain between two posts in a shallow curve called a catenary.’
- ‘In the final work in this show Johns uses the simplest of motifs, a catenary line; the curve of a cord hanging between two points.’
- ‘The Choo Choo also has a New Orleans Streetcar ride through the complex, complete with a catenary wire. We decided we would ride this at 4 PM, after our return from the tourist train trip.’
- ‘Because of opposition to a catenary system, the surface system uses busses powered by compressed natural gas.’
- ‘In mathematics Jungius proved that the catenary is not a parabola (Galileo assumed it was).’
- ‘Suspended by a network of tensile wires from a central mast, this inverted catenary roof consists of five planes moored to two smaller secondary masts at each end.’
- ‘He met Johann Bernoulli in 1691, shortly after the latter had made his discovery of the catenary.’
- ‘What are the curvatures, which combine to define the catenary function?’
- 1.1 A wire, rope, or chain forming a catenary.
- ‘This was another eight-minute trip, during which we did the reverse procedure, switching from catenary to third rail power.’
- ‘Metro North continues to have one track totally out of service for bridge and catenary repairs.’
- ‘On the way, we passed underneath the METRA line we had ridden earlier, over a waterway, past the Skokie Shops, and experienced a power change as the train switched from third rail to overhead catenary power.’
- ‘Howard Street has some tracks and catenary that resembles those found along St. Charles, but except for the St. Charles Streetcars in one direction, they are not used on Howard.’
- ‘If we look at that, then look at bridges and catenaries, and teach the principles.’
- ‘Another innovation is a system of steel catenary cables embedded in floor slabs.’
- ‘The electric part is that it uses a pantograph or roof mounted current collector to pick up electricity from the overhead catenary or wires - the same ones that zapped little Timu a few days ago.’
- ‘Once onto the actual branch, old catenary towers are visible, a reminder that this line was once electrified.’
- ‘But he ran through the portal before the track was laid, and he climbed a catenary pole, and was electrocuted.’
- ‘We were going to be in Kansas City, but not by the route used by Amtrak, that will soon have catenary.’
- ‘He used as reference the catenary cables of the RENFE train line that crosses the community as well as the horizon delineated by the mountains surrounding the area.’
- ‘It looks like a spider's web above the tracks with all the catenary, although rumor has it that one of the two new tracks will be ‘unplugged’ as it where.’
- ‘The line uses a single Arrow III MU coach, running under catenary just like its much larger siblings on the other electrified lines.’
- ‘I later found out that the problem was a transformer fire in the Bronx, which resulted in a loss of power to the overhead catenary along the Hell Gate Bridge line.’
- ‘To add certainty to these movements, the officers used the cables of the RENFE catenary and the mountains in the background as a point of reference.’
- ‘They recently opened electrification from Windsor to Blainville, and they electrified the track between CP and CN tracks, using overhead catenary the whole way.’
- ‘We were able to see the concrete abutments where there were once catenary towers.’
- ‘At Morrisville we pass the old flyover for the PRR Trenton Cut-off freight line. It has been rehabbed and new catenary installed.’
- ‘The Village luminaires feature pole, wall and catenary mounted fittings that correspond with the other site furnishings.’
